Now you can save on the gas you put in your car, just by buying groceries! Bi-Lo Fuelperks is a reward system that will enable you to a certain amount off of the cost of a gallon of gas at a participating gas station. You will need a Bi-Lo bonus card to start accruing fuelperks. Then take your bonus card to the gas pump, swipe it and get your discount on up to 20 gallons of gas.
