A computer is used to receive data, including an amount of fuel to which a fuel benefit will apply, and a nominated price for the fuel for a future period, from a driver of a motor vehicle. During the future period, or after the future period has passed, purchase data is received, including a quantity of fuel purchased by the driver during the period, and a price paid for the purchased fuel. The purchase price is compared with the nominated price, and if the purchase price is higher than the nominated price, a refund is issued to the driver of at least a portion of the difference between the purchase price and the nominated price, for at least some of the quantity of fuel purchased. |
