[0045] According to the embodiment, when delivering the sewing machine 2 to the user after use, the transfer price of the sewing machine 2 is appropriately determined based on the operation history data. For the sewing machine 2 operated under severe operating conditions, it is more advantageous for the user to have a lower transfer price. On the other hand, if the sewing machine 2 operated under non-severe operating conditions is delivered to the user at a low price, it is disadvantageous to the delivery operator. According to the embodiment, since an appropriate transfer price of the sewing machine 2 is determined based on the operation history data, it is possible to suppress at least one of the delivery operator and the user from being disadvantaged.

[0046] In an embodiment, based on the usage environment history data, the delivery price of the sewing machine 2 is appropriately determined. For the sewing machine 2 that has operated in a harsh usage environment, it is more advantageous for the user to have a lower delivery price. On the other hand, delivering the sewing machine 2 that has operated in a non-harsh usage environment to the user at a low price is disadvantageous to the delivery business operator. According to the embodiment, since the appropriate delivery price of the sewing machine 2 is determined based on the usage environment history data, it is suppressed that at least one of the delivery business operator and the user is disadvantaged.

[0047] In an embodiment, based on the maintenance history data, the sewing machine 2 is appropriately maintained. For example, for the sewing machine 2 with a low maintenance frequency, it is more advantageous for the user to have a lower delivery price. On the other hand, delivering the sewing machine 2 that has been maintained meticulously and frequently to the user at a low price is disadvantageous to the delivery business operator.
