Today's tip: Join the club
Members of warehouse clubs, such as Sam's Club, Costco and BJ's enjoy lower prices at the pump. (In my area, it's usually 5 to 6 cents a gallon cheaper)
Also, some gasoline retailers have loyalty programs. Every time you buy something, you earn points. Earn enough points and you can get gift cards, or a few cents off a gallon.
Speaking of clubs, do you belong to a motor club, a union or any other organization? Check their benefits. The motor club in my area occasionally offers gas cards at a discount
