A computer-implemented method of providing a discount for fuel to a customer is disclosed. The method includes identifying a customer to a retail store using a first reader device in operative communication with a host computer, which is communication with an identification module. The identification module creates and associates a customer with a customer identification record. A preliminary award record is created and maintained, which includes a discount-per-gallon award for fuel associated with the customer identification record in response to a purchase recognized by the host computer. The host computer adds subsequent preliminary award records to the preliminary award record associated with a customer identification to create an intermediate award record, which includes all the discount-per-gallon awards associated with the customer. A purchase of fuel is initiated by the purchaser at a fuel station with at least one fuel pump. The customer is identified by the fuel pump controller in operative communication with both a second reader device and a second identification module. The intermediate award record is retrieved by the host computer from a database and the host computer recognizes that the customer is eligible for a fuel station supplementary discount. A final discount record received by the customer and the customer is provided with the final discount associated with the final discount award record.
