Buy Groceries with a Card: $3.20 Each Time You Get Gas
Many supermarkets have loyalty cards that reward shoppers with discounts on future purchases. Price Chopper, Kroger, Safeway, Winn-Dixie and other chains, though, have started giving their regular customers discounted gas at participating stations. The discount varies by program, but customers typically receive a 20-cent-per-gallon reduction for spending $200 on groceries. With the national average cost of a gallon of gas currently at $3.23, a 16-gallon tank of gas costs $51.68. Knocking 20 cents off each gallon drops the cost to $48.48.
