[0072] In one embodiment, in response to receiving a first user input, the electronic device (110) may display a purchase option page including at least one candidate option on the user terminal. A product trading platform may store multiple candidate options for purchasing a target product. Each of the multiple candidate options corresponding to the target product may represent a purchase option that sells the target product with a different sales volume. Furthermore, the unit price of the target product may decrease as the sales volume of each of the multiple candidate options corresponding to the target product increases. The purchase option page may include at least one candidate option among the multiple candidate options corresponding to the target product.

[0073] For example, the electronic device (110) can directly generate a purchase option page and transmit it to the user terminal (120). Through this, the user terminal (120) can output the purchase option page received from the electronic device (110) on the screen of the user terminal (120). However, the present invention is not limited thereto, and the electronic device (110) can also transmit only the information to be included in the purchase option page to the user terminal (120). In this case, the user terminal (120) can generate a purchase option page using the information received from the electronic device (110) and output it on the screen of the user terminal (120).

[0074] In this specification, when it is described that an electronic device (110) generates a page (e.g., a purchase options page) and transmits it to a user terminal (120), it should be understood that only the information to be included in the page may be transmitted to the user terminal (120), and the user terminal (120) may also generate the page. Similarly, when it is described that a user terminal (120) generates and outputs a page, it should be understood that the electronic device (110) may also generate the page and transmit it to the user terminal (120).

[0075] In one embodiment, the purchase option page corresponding to the target product may include at least one of a first option change page and a second option change page. Furthermore, at least one candidate option included in the purchase option page corresponding to the target product may include a reference option corresponding to the first product, but is not limited thereto. At least one candidate option included in the purchase option page may not include a reference option. For convenience of explanation, the following description primarily describes a situation where at least one candidate option included in the purchase option page corresponding to the target product includes a reference option corresponding to the first product.

[0076] In operation (S330), the electronic device (110) may receive a second user input for selecting a target option from at least one candidate option through a purchase option page. In particular, the second user input may be an input requesting a change in the purchase option of a target product included in the user's purchase list to the target option.

[0077] In one embodiment, a user may transmit a second user input to the electronic device (110) via the user terminal (120) requesting a change in a purchase option of a target product included in the user's purchase list. The second user input may represent a user input to the user terminal (120), for example, a user input of touching or tapping at least a portion of an icon displayed in an area corresponding to a target option included in a purchase option page.

[0078] In operation (S340), in response to receiving a second user input, the electronic device (110) can change the purchase option of the target product added to the purchase list from the reference option to the target option.

[0079] In one embodiment, in response to receiving a second user input, the electronic device (110) may delete all target products to which the standard option is applied, included in the user's purchase list, regardless of the purchase quantity, and increase the purchase quantity of target products to which the target option is applied by one. However, the present invention is not limited thereto, and in response to receiving a second user input, the electronic device (110) may decrease the purchase quantity of target products to which the standard option is applied, included in the user's purchase list, by only one, while increasing the purchase quantity of target products to which the target option is applied by one. In this case, the electronic device (110) may adjust the purchase quantity of target products to which the target option is applied to be included in the purchase list, at the user's request.

[0080] In the above-described embodiment, at least one candidate option included in the purchase option page is described as a purchase option that sells the target product with a different sales volume. However, the present invention is not limited thereto, and the electronic device (110) may, in response to receiving a first user input, display a purchase option page on the user terminal (120) that includes purchase options for purchasing a different product from the target product. The purchase option page may include purchase options for the target product along with purchase options for other products belonging to the same or similar category as the target product. For example, if the target product is a lemon sold by Company A, the electronic device (110) may include a second purchase option for purchasing a lemon sold by Company B (a different product) in addition to a first purchase option for purchasing a lemon from Company A (the target product) to provide the user with more choices. Lemons from Company A may represent products in the same category as lemons from Company B. In this case, when the electronic device (110) receives a user input selecting the second purchase option, the electronic device (110) may change the products stored in the user's purchase list. However, in the following specification, for convenience of explanation, it is mainly explained that at least one candidate option included in the purchase option page is a purchase option for purchasing the same target product.

[0081] FIG. 4 is a diagram showing a product list page output from a user terminal according to one embodiment of the present disclosure.

[0082] In one embodiment, the electronic device (110) may generate a product list page (410) and transmit it to the user terminal (120). The user terminal (120) may output the product list page (410) received from the electronic device (110) on the screen of the user terminal (120). The product list page (410) may display information regarding each of a plurality of products (420, 430, 440).

[0083] In one embodiment, the electronic device (110) may receive a first user input from the user terminal (120) to select a first icon (421) for purchasing a first product (420) included in a product list page (410). In response to receiving the first user input, the electronic device (110) may automatically add a target product to which a reference option corresponding to the first product (420) has been applied to the user's purchase plan list (e.g., a shopping cart) without any additional input from the user. At this time, information (422) indicating the purchase quantity (e.g., 3) of the target product to which the reference option has been applied, included in the user's purchase plan list, may be displayed in an area corresponding to the first product (420) included in the product list page (410). For example, as illustrated in FIG. 4, the electronic device (110) may receive a first user input from the user terminal (120) to select a first icon (430) when the user's purchase plan list already includes a target product to which the reference option has been applied. In this case, since the purchase quantity of the target product to which the standard option included in the user's purchase list is applied increases to 4, the information (422) may be updated to indicate a purchase quantity of 4. The electronic device (110) may display a purchase option page corresponding to the target product on the user terminal (120) simultaneously with the update of the information (422). The purchase option page may be overlaid on a page (e.g., product list page (410)) that is currently being output on the screen of the user terminal (120) or may be displayed in the form of a sidebar.

[0084] FIGS. 5 and 6 are diagrams showing a purchase option page output from a user terminal according to one embodiment of the present disclosure.

[0085] In one embodiment, in response to receiving a first user input, the electronic device (110) may cause a purchase option page including at least one candidate option to be displayed on the user terminal (120). The electronic device (110) may cause at least one of the first option change page (510) and the second option change page (610) to be displayed as the purchase option page on the user terminal (120). The number of purchase options for the target product included in the first option change page (510) may be less than the number of purchase options for the target product included in the second option change page (610).

[0086] FIG. 5 is a diagram illustrating a first purchase option page (510) output from a user terminal (120). In one embodiment, the electronic device (110) may cause the first option change page (510) to be displayed on the user terminal (120). The first option change page (510) may include at least one candidate option selected from among a plurality of candidate options for the purchase of a target product. For example, the electronic device (110) may generate the first option change page (510) to include at least one candidate option from among a plurality of candidate options for the purchase of a target product and transmit the first option change page (510) to the user terminal (120). Referring to FIG. 6, the electronic device (110) may cause the second option change page (610) to be displayed on the user terminal (120). The second option change page (610) may include all of the plurality of candidate options for the purchase of a target product. For example, the electronic device (110) may generate a second option change page (610) to include all of the multiple candidate options for purchasing the target product and transmit it to the user terminal (120).

[0087] In one embodiment, the electronic device (110) may cause a second option change page (610) to be displayed after the first option change page (510) is displayed on the user terminal (120). Referring again to FIG. 5, the first option change page (510) may additionally include a second icon (511) for calling the second option change page (610). The electronic device (110) may receive a third user input for selecting the second icon (511) for calling all of a plurality of candidate options for purchasing a target product while the first option change page (510) is displayed on the user terminal (120). In response to receiving the third user input, the electronic device (110) may cause the second option change page (610) to be displayed on the user terminal (120).

[0088] In one embodiment, information (521) indicating that a target product to which the target option (520) has been applied has been added to the user's purchase list may be displayed in an area corresponding to a reference option (520) included in a first option change page (510). The first option change page (510) may include other candidate options (530) in addition to the reference option (520). In an area corresponding to other candidate options (530) included in the first option change page (510), a third icon (531) may be displayed for changing, that is, deleting a target product to which the target option (520) has been applied from the user's purchase list and adding a target product to which another candidate option (530) has been applied. The first option change page (510) may include an icon (540) for calling a shopping cart page for purchasing a product stored in the user's purchase list.

[0089] In one embodiment, the second option change page (610) may include all of a plurality of candidate options (620, 630, 640, 650, 660) for purchasing a target product. In an area corresponding to a reference option (620) included in the second option change page (610), information (621) indicating that a target product to which the reference option (620) has been applied has been added to the user's purchase list may be displayed. In an area corresponding to each of the other candidate options (630, 640, 650, 660) except for the reference option (620) included in the second option change page (610), a third icon for changing, i.e., deleting a target product to which the reference option (620) has been applied from the user's purchase list and adding a target product to which each other candidate option has been applied, may be individually displayed.

[0090] In one embodiment, the electronic device (110) may cause the second option change page (610) to be displayed directly on the user terminal (120) without displaying the first option change page (510). In one embodiment, the electronic device (110) may determine whether to display the first option change page (510) before the second option change page (610) based on an option change rate calculated for each option change page. Specifically, the electronic device (110) may calculate a first option change rate indicating a rate at which users of a product transaction service change purchase options of a target product through the first option change page (510). The electronic device (110) may calculate a second option change rate indicating a rate at which users of a product transaction service change purchase options of a target product through the second option change page (510). The electronic device (110) may determine whether to display either the first option change page or the second option change page on the user terminal (120) based on a comparison of the first option change rate and the second option change rate. For example, if the first option change rate is greater than the second option change rate, the electronic device (110) determines that users of the product transaction service frequently change the purchase options of the target product through the first option change page (510) rather than the second option change page (610), and thus may cause the first option change page (510) to be displayed as the purchase option page on the user terminal (120). On the other hand, if the second option change rate is greater than the first option change rate, the electronic device (110) determines that users of the product transaction service frequently change the purchase options of the target product through the second option change page (610) rather than the first option change page (510), and thus may cause the second option change page (610) to be displayed on the user terminal (120) directly without displaying the first option change page (510).The option change rate may represent the ratio of the number of buyers who changed the purchase option of the target product through a specific option change page (e.g., first option change page, second option change page) to the total number of buyers who changed the purchase option of the target product at least once and purchased the target product.

[0091] FIG. 7 is a diagram illustrating a process of selecting two or more candidate options to be included in a first option change page by an electronic device according to one embodiment of the present disclosure.

[0092] In one embodiment, the electronic device (110) may select candidate options to be included in a first option change page (510) among a plurality of candidate options for purchasing a target product. Below, candidate options that may be included in the first option change page (510) will be described.

[0093] In one embodiment, the electronic device (110) may select a first candidate option (e.g., candidate option (730)) corresponding to the next highest sales capacity (e.g., 2 kg, 1 kg x 2) by comparing the sales capacity corresponding to the reference option (720) among a plurality of candidate options. The electronic device (110) may select the first candidate option (e.g., candidate option (730)) as a candidate option to be included in the first option change page (510). Alternatively, the electronic device (110) may select the reference option (720) and the first candidate option (e.g., candidate option (730)) as candidate options to be included in the first option change page (510) so as to facilitate comparison between the reference option (720) and the first candidate option. The electronic device (110) can induce a user to purchase a target product with a higher sales capacity than the reference option without a large price burden by including a first candidate option (e.g., candidate option (730)) in the first option change page (510).

[0094] In one embodiment, the electronic device (110) may select a second candidate option (e.g., candidate option (740)) that corresponds to the sales capacity (e.g., 1 kg, 1 kg × 1 unit) corresponding to the reference option (720) among a plurality of candidate options and the closest sales capacity (e.g., 3 kg, 1 kg × 3 units) to the product of the purchase quantity (e.g., 3 units) for the reference option (720) and the value (e.g., 3 kg). At this time, the purchase quantity (e.g., 3 units) for the reference option (720) may represent the purchase quantity of a target product to which the reference option is applied, stored in the user's purchase list. For example, the purchase quantity for the reference option (720) may represent the purchase quantity after the electronic device (110) increases the purchase quantity of a target product to which the reference option is applied in the user's purchase list by one in response to receiving a first user input. The electronic device (110) may select the second candidate option (e.g., candidate option (740)) as a candidate option to be included in the first option change page (510). Alternatively, the electronic device (110) may select the reference option (720) and the second candidate option (e.g., candidate option (740)) as candidate options to be included in the first option change page (510) so that comparison between the reference option (720) and the second candidate option can be facilitated. By including the second candidate option (e.g., candidate option (740)) in the first option change page (510), the electronic device (110) may provide a cost-effective purchasing option that matches the overall sales volume of the target product that the user plans to purchase, which may contribute to reducing the user's cost burden.

[0095] In one embodiment, the electronic device (110) may select candidate options to be included in the first option change page (510) by considering the unit price of the target product corresponding to the purchase option. More specifically, the electronic device (110) may calculate the difference between the unit price of the target product corresponding to each candidate option and the unit price of the target product corresponding to the candidate option corresponding to the next lower sales volume as the price discount increase of each candidate option, for each of the plurality of candidate options. The unit price may represent the price per unit volume of the target product. For example, the unit volume of the target product may be 100g, but is not limited thereto, and the unit volume may vary depending on the category of the target product. The price discount increase of the candidate option (730) can be calculated as the difference (e.g., 50 won) between the unit price (e.g., 950 won) of the target product corresponding to the candidate option (730) and the unit price (e.g., 1,000 won) of the target product corresponding to the candidate option (e.g., the reference option (720)) corresponding to the next lower sales volume (e.g., 1 kg, 1 kg × 1 unit) compared to the sales volume (e.g., 1 kg, 1 kg × 2 units) corresponding to the candidate option (730). Similarly, the price discount increase of the candidate option (740) can be calculated as the difference (e.g., 10 won) between the unit price (e.g., 940 won) of the target product corresponding to the candidate option (740) and the unit price (e.g., 950 won) of the target product corresponding to the candidate option (740). As a result, the electronic device (110) can select a third candidate option (e.g., candidate option (760)) with the largest price discount increase among the plurality of candidate options, and can select the third candidate option (e.g., candidate option (760)) as a candidate option to be included in the first option change page (510).Alternatively, the electronic device (110) may select the reference option (720) and the third candidate option (e.g., candidate option (760)) as candidate options to be included in the first option change page (510) to facilitate comparison between the reference option (720) and the third candidate option. By including the third candidate option (e.g., candidate option (760)) in the first option change page (510), the electronic device (110) may provide the user with a purchase option that offers a relatively high discount rate, thereby increasing the user's desire to purchase the target product.

[0096] In one embodiment, the electronic device (110) may select a fourth candidate option (e.g., candidate option (750)) that users of a product transaction service most frequently purchase when purchasing a target product, and a fifth candidate option (e.g., candidate option (740)) that users most frequently select as a target option through a purchase option page when purchasing a target product, among a plurality of candidate options. The electronic device (110) may select at least one of the fourth candidate option (e.g., candidate option (750)) and the fifth candidate option (e.g., candidate option (740)) as a candidate option to be included in the first option change page (510). Alternatively, the electronic device (110) may select at least one of the fourth candidate option (e.g., candidate option (750)) and the fifth candidate option (e.g., candidate option (740)) and the reference option (720) as candidate options to be included in the first option change page (510) so as to facilitate comparison between the reference option (720) and the fourth and / or fifth candidate options. In one embodiment, when the fourth candidate option that users of the product transaction service most frequently purchase when purchasing the target product or the fifth candidate option that users most frequently select as a target option through the purchase option page when purchasing the target product are updated over time, the candidate options included in the first option change page (510) may also be updated. The fourth candidate option may be the same as or different from the fifth candidate option. The fourth candidate option may be described as the purchase option that all purchasers of the target product most frequently select when purchasing the target product, and the fifth candidate option may be described as the purchase option that purchasers of the target product most frequently change during the purchase process of the target product by changing the purchase option of the target product.For example, if the electronic device (110) includes a fourth candidate option (e.g., candidate option (750)) in the first option change page (510), the electronic device (110) may additionally display information regarding a selection rate of the fourth candidate option (e.g., candidate option (750)) in an area corresponding to the fourth candidate option (e.g., candidate option (750)) included in the first option change page (510). Here, the selection rate of the fourth candidate option may represent the ratio of the number of buyers who purchased the target product through the fourth candidate option to the total number of buyers of the target product. If the electronic device (110) includes a fifth candidate option (e.g., candidate option (740)) in the first option change page (510), the electronic device (110) may additionally display information regarding a change rate to the fifth candidate option (e.g., candidate option (740)) in an area corresponding to the fifth candidate option (e.g., candidate option (740)) included in the first option change page (510). The change rate of the fifth candidate option can be expressed as the ratio of the number of buyers who changed the purchase option of the target product and purchased the target product to the number of buyers who changed the purchase option of the target product and purchased the target product.

[0097] In one embodiment, the electronic device (110) may select candidate options to be included in the first option change page (510) based on calculating a score corresponding to the purchase option. More specifically, the electronic device (110) may calculate a score corresponding to each of the plurality of candidate options based on at least one of a preference of each of the plurality of candidate options, a sales volume corresponding to each of the plurality of candidate options, and a unit price of a target product corresponding to each of the plurality of candidate options. The electronic device (110) may select one or more candidate options having a score higher than a threshold score among the plurality of candidate options as candidate options to be included in the first option change page (510). Alternatively, the electronic device (110) may select the reference option (720) and one or more candidate options having a score higher than the threshold score as candidate options to be included in the first option change page (510) so as to facilitate comparison between the reference option (720) and the one or more candidate options having a score higher than the threshold score.

[0098] For example, the electronic device (110) may calculate a higher score for a candidate option as the preference for the candidate option increases. The preference for a candidate option may indicate the degree to which at least one of the purchasers and users of the target product prefers the candidate option when purchasing the target product. The preference for a candidate option may be determined using various factors, such as the purchase information of the purchasers of the target product, the user's purchase history information, and the product category of the target product. The preference for a candidate option may be proportional to the selection rate of the candidate option, which is the ratio of the number of purchasers who purchased the target product through the candidate option to the number of purchasers who purchased the target product. Furthermore, the preference for a candidate option may increase as the sales volume corresponding to the candidate option approaches the sales volume derived from the user's purchase history information, which is a value derived from the user's purchase history information, indicating that the user purchased products in a similar category to the target product or frequently purchased products when purchasing the target product. In another example, the electronic device (110) may calculate a higher score for a candidate option as the sales volume corresponding to the candidate option approaches the value obtained by multiplying the sales volume corresponding to the reference option by the purchase quantity for the reference option. Conversely, the electronic device (110) may calculate a lower score for a candidate option when the difference between the sales capacity corresponding to the candidate option and the sales capacity corresponding to the reference option is greater. For another example, the electronic device (110) may calculate a higher score for a candidate option when the unit price of the target product corresponding to the candidate option is lower. In summary, the score for a purchase option may be determined based on, but is not limited to, the preference for the candidate option, the sales capacity corresponding to the candidate option, and the unit price of the target product corresponding to the candidate option. Any factor that may influence the user's selection of a purchase option for the target product may be sufficiently additionally considered when calculating the score for the candidate option.

[0099] FIG. 8 is a diagram illustrating a process in which a user terminal according to one embodiment of the present disclosure outputs a first option change page in which the number of purchase options is increased.

[0100] In one embodiment, the electronic device (110) may adjust the number of purchase options included in the first option change page (811). The electronic device (110) may accumulate the number of times it receives a third user input selecting a second icon (821) for calling a second option change page (620) included in the first option change page (811). In response to the fact that the number of accumulated third user inputs is greater than or equal to a threshold number, the electronic device (110) may increase the number of purchase options included in the first option change page (811). In addition, the electronic device (110) may also initialize the number of accumulated third user inputs. The threshold number may be, but is not limited to, five. For example, the electronic device (110) may increase the number of purchase options included in the first option change page (811) by one. Referring to FIG. 8, the existing first option change page (811) may include only two purchase options, including a reference option. In response to the fact that the number of accumulated third user inputs for selecting the second icon (821) included in the existing first option change page (811) is five or more, the electronic device (110) may increase the number of purchase options included in the existing first option change page (811) by one, and accordingly, may cause the updated first option change page (812) including three purchase options to be displayed on the user terminal (120). That is, when the number of accumulated third user inputs is five or more, and when the electronic device (110) receives the first user input for selecting the first icon corresponding to the next first product, the electronic device (110) may cause the updated first option change page (812) to be displayed on the user terminal (120). At this time, the updated first option change page (812) may include the purchase options included in the existing first option change page (811).For example, the purchase option (830) added to the updated first option change page (812) may be, but is not limited to, a candidate option with the smallest sales volume among the candidate options excluding the candidate options included in the existing first option change page (811). The updated first option change page (812) may include a second icon (822) for calling the second option change page (620). The electronic device (110) may initialize the number of times a third user input for selecting the second icon (821) included in the existing first option change page (811) is received when the number of times a third user input for selecting the second icon (821) included in the existing first option change page (811) reaches 5 or more. In addition, the electronic device (110) may accumulate the number of times a third user input for selecting the second icon (822) included in the updated first option change page (812) is received. The electronic device (110) may increase the number of purchase options included in the updated first option change page (812) by one in response to a third user input selecting the second icon (822) being greater than or equal to a threshold number of times.

[0101] FIGS. 9 and 10 are diagrams showing a purchase option page displaying benefit information output from a user terminal according to one embodiment of the present disclosure.

[0102] In one embodiment, the electronic device (110) may display information about benefits that a specific candidate option has compared to a reference option in an area corresponding to a specific candidate option within a purchase option page (e.g., a first option change page, a second option change page) that includes at least one candidate option.

[0103] Referring to FIG. 9, the electronic device (110) may display information (931) indicating that the target product is sold at the lowest unit price among the candidate options (930) among at least one candidate option in the purchase option page (910) as benefit information in an area corresponding to the candidate option (930) having the lowest unit price of the target product. In addition, the electronic device (110) may display information (941) indicating that the target product is the most preferred option by users of the product transaction service when purchasing the target product as benefit information in an area corresponding to the purchase option (e.g., candidate option (940)) most frequently purchased by users of the product transaction service when purchasing the target product among at least one candidate option in the purchase option page (910). In addition, the electronic device (110) may display various benefit information on the purchase option page (910).

[0104] Figure 10 illustrates a purchase option page (1011, 1012) displaying benefit information related to a sale price. In one embodiment, the electronic device (110) may calculate first discount information representing the difference between the sale price corresponding to a specific candidate option and a price calculated by multiplying the sale price corresponding to the reference option by a value obtained by dividing the sale capacity corresponding to the specific candidate option by the sale capacity corresponding to the reference option, and may display the first discount information as benefit information. For example, the electronic device (110) can calculate first discount information (1031) representing the difference (e.g., 1,000 won) between the sales price (e.g., 19,000 won) corresponding to the candidate option (1030) on the purchase option page (1011) and the price (e.g., 20,000 won) calculated by multiplying the sales capacity (e.g., 2 kg, 1 kg x 2 units) corresponding to the candidate option (1030) by the sales capacity (e.g., 1 kg, 1 kg x 1 unit) corresponding to the reference option (1020) by the value (e.g., 2) and the sales price (e.g., 10,000 won) corresponding to the reference option (1020), and can display the first discount information (1031) as benefit information in an area corresponding to the candidate option (1030) included in the purchase option page (1011). The electronic device (110) displays the first discount information (1031) as benefit information on the purchase option page (1011), thereby allowing the user to intuitively provide the amount of money that can be saved by comparing the selling price of the candidate option (1030) with the price when purchasing the sales capacity corresponding to the candidate option (1030) through the standard option (1020).

[0105] In one embodiment, the electronic device (110) may calculate second discount information indicating a difference between the unit price of a target product corresponding to a specific candidate option and the unit price of a target product corresponding to a reference option, and may display the second discount information as benefit information. For example, the electronic device (110) may calculate second discount information (1032) indicating a difference (e.g., 50 won) between the unit price (e.g., 950 won) of a target product corresponding to a candidate option (1030) and the unit price (e.g., 1,000 won) of a target product corresponding to a reference option (1020) on a purchase option page (1012), and may display the second discount information (1032) as benefit information in an area corresponding to the candidate option (1030) included on the purchase option page (1012). The electronic device (110) can intuitively provide the user with the amount that can be saved per unit capacity of the target product when the user purchases the target product through the candidate option (1030) by displaying the second discount information (1032) as benefit information on the purchase option page (1012).

[0106] In one embodiment, the electronic device (110) may, in response to changing the purchase option of a target product added to the user's purchase list from a reference option to a target option, update benefit information displayed on a purchase option page based on the target option. For example, when the user terminal (120) receives a second user input selecting a third icon (1040) corresponding to a candidate option (1030), the user terminal (120) may change the purchase option of the target product in the user's purchase list to the candidate option (1030) and update benefit information displayed on purchase option pages (1011, 1012) based on the candidate option (1030). In an area corresponding to the candidate option (1030) included in the purchase option pages (1011, 1012), instead of benefit information (e.g., first discount information (1031), second discount information (1032)), information indicating that a target product to which the candidate option (1030) has been applied has been added to the user's purchase list may be displayed. In addition, in the area corresponding to the standard option (1020) in the purchase option page (1011, 1012), first discount information or second discount information for the standard option (1020) calculated based on the candidate option (1030) may be displayed. For example, the first discount information for the standard option (1020) may be information (e.g., 'Buy 1 and it's 500 won more expensive') indicating the difference between the selling price (e.g., 10,000 won) of the standard option (1020) and the price (e.g., 9,500 won) when purchasing the sales quantity corresponding to the standard option (1020) through the candidate option (1030). The second discount information for the standard option (1020) may be information (e.g., 'Buy 1 and it's 500 won more expensive') regarding the amount that can be saved per unit quantity of the target product when purchasing the target product through the standard option (1020), but is not limited thereto.Furthermore, if the purchase option page (1011, 1012) includes other candidate options (not shown) in addition to the reference option (1020), the electronic device (110) may display first discount information or second discount information for other candidate options recalculated based on the candidate option (1030) in an area corresponding to the other candidate options within the purchase option page (1011, 1012).

[0107] Furthermore, when the electronic device (110) receives a second user input selecting a third icon (1040) corresponding to a candidate option (1030), the electronic device (110) may change the purchase options included in the purchase option pages (1011, 1012) based on the candidate option (1030). For example, the electronic device (110) may delete candidate options having a sales capacity smaller than the sales capacity corresponding to the candidate option (1030) on the purchase option pages (1011, 1012) and include candidate options having a sales capacity larger than the sales capacity corresponding to the candidate option (1030), but is not limited thereto. In this case, the electronic device (110) may display benefit information for each candidate option included in the purchase option pages (1011, 1012) based on the candidate option (1030).

[0108] As described above, when the user terminal (120) receives a second user input for selecting a target option through the purchase option page, the user terminal (120) may update the benefit information displayed on the purchase option page (1011, 1012) while maintaining the output of the purchase option page (1011, 1012), but may also immediately terminate the output of the purchase option page (1011, 1012). For example, if the purchase option page (1011, 1012) was overlaid on the product list page (410), the user terminal (120) may activate and output the product list page (410) along with the termination of the output of the purchase option page (1011, 1012).

[0109] FIG. 11 is a diagram showing a product list page output after the output of a purchase option page is terminated in a user terminal according to one embodiment of the present disclosure.

[0110] In one embodiment, an area corresponding to each product displayed on the product list page (1110) may indicate whether the product has been added to the purchase list. The electronic device (110) may delete an indication that the first product has been added to the purchase list from an area corresponding to the first product (not shown) included in the product list page (1110). Referring to FIG. 4 , the electronic device (110) may delete information (422) indicating the purchase quantity of a target product to which a standard option included in the user's purchase list has been applied, which was included in the product list page (1110). In addition, the electronic device (110) may display an indication that the second product (1120) has been added to the purchase list in an area corresponding to the second product (1120) included in the product list page (1110). In this case, the second product (1120) may indicate a product corresponding to a target option of the target product. In other words, information (1122) indicating the purchase quantity (e.g., 1) of a target product to which a target option included in the user's purchase list is applied may be displayed in an area corresponding to a second product (1120) included in a product list page (1110).

[0111] Referring to FIG. 11, after the output of the purchase option page is terminated according to the selection of the target option of the target product, the electronic device (110) may automatically scroll the product list page (1110) so that an area corresponding to a second product (1120) included in the product list page (1110) is displayed on the screen of the user terminal (120). The electronic device (110) may cause an area corresponding to the second product (1120) in the product list page (1110) to be displayed on the screen of the user terminal (120), thereby allowing the user to visually confirm that a first product (not shown) is deleted and a second product (1120) is added from the user's purchase list. The user may cause the user terminal (120) to display a purchase option page including at least one candidate option for changing the purchase option of the target product by selecting a first icon (1121) for purchasing the second product (1120).

[0112] In one embodiment, after the output of the purchase option page on the user terminal (120) is terminated, the electronic device (110) may display a pop-up message (1130) containing information that the purchase option of a target product included in the user's purchase list has changed on the product list page (1110). The pop-up message (1130) may include an icon (1131) that allows landing on a shopping cart page for purchasing a product stored in the user's purchase list (e.g., shopping cart). For example, the electronic device (110) may display the pop-up message (1130) on the product list page (1110) for a preset period of time from the time when the output of the purchase option page is terminated. The preset period of time may be 2 seconds, but is not limited thereto.

[0113] FIG. 12 is a diagram showing a shopping cart page output from a user terminal according to one embodiment of the present disclosure.

[0114] In one embodiment, the electronic device (110) may cause a shopping cart page (1210) to be displayed on a user terminal (120). For example, when the electronic device (110) receives a user input for selecting an icon (540) for calling the shopping cart page (1210) included in an option change page (510), or receives a user input for selecting an icon (1131) included in a pop-up message (1130) displayed on a product list page (1110), the electronic device (110) may cause the shopping cart page (1210) to be displayed on the user terminal (120). However, the method for causing the electronic device (110) to display the shopping cart page (1210) on the user terminal (120) is not limited thereto.

[0115] In one embodiment, the shopping cart page (1210) may display information (1221) regarding target options. For example, the information (1221) regarding target options may include the sales capacity of the target product corresponding to the target option, the sales price of the target product corresponding to the target option, the purchase quantity for the target option, and the expected arrival time of the target product to which the target option is applied.

[0116] In one embodiment, when the purchase option of a target product included in a purchase list (e.g., a shopping cart) is changed from a reference option to a target option, the electronic device (110) may set the shopping cart page (1210) to automatically include the target product with the target option applied in the list for the user's final payment. In other words, the user must select a product for which the final payment is to be made among the products included in the shopping cart page (1210) and include it in the list for the final payment. The electronic device (110) may automatically activate the checkbox (1222) for including the target product with the target option applied in the list for the final payment on the shopping cart page (1210). The electronic device (110) may determine that the change in the purchase option of the target product indicates a high purchase intention of the user, and may activate the checkbox (1222) of the target product with the target option applied in advance without the user having to directly activate it.

[0117] The methods according to the present disclosure may be computer-implemented. The computer may, for example, include an electronic device capable of performing processing.
