In order to distribute coupons to a consumer computer a link is established with a coupon server, in response to which the coupon server transmits a file containing a list of participating retail outlets. In response to the consumer's selection of a retail outlet, the coupon server transmits a file containing the inventory of goods offered for sale by the selected retail outlet and data representative of the physical layout of the selected retail outlet indicating the aisle location of the goods. The inventory is displayed by the consumer computer such that each item of goods is individually selectable. The consumer may thus enter a shopping list by selecting one or more items of goods he or she intends to purchase at the selected retail outlet. In response to the selection of goods, the coupon server transmits to the consumer computer a file containing electronic coupons corresponding to one or more of the selected goods and a file containing data identifying the aisle location in the selected retail outlet of the goods selected by the consumer.

A brake apparatus for a vehicle generally sets an upper limit value of regenerative braking force to the maximum value of the regenerative braking force which can be generated at the present. In the case of a front-wheel-drive vehicle, the total braking force, the sum of front-wheel braking force (front-wheel hydraulic braking force+regenerative braking force) and rear-wheel braking force (rear-wheel hydraulic braking force), is rendered coincident with a target braking force corresponding to a brake pedal depressing force, and the regenerative braking force is set to a largest possible value equal to or less than the upper limit value. As a result, the regenerative braking force can be larger than front-wheel-side target distribution braking force. The upper limit value is decreased from the maximum value by an amount corresponding to the degree of easiness of occurrence of a locking tendency at the driven wheels (front wheels).
