No one likes to be tied down to using just one gas station chain or convenience store location, no matter how convenient it is. But don’t worry; it’s still worth signing up for a customer rewards card at a store you only use some of the time. Because this card is a rewards card, not a credit card, there’s no harm in signing up for it, even if you don’t use it that often. The thing to consider is whether it might be an even better idea to also sign up for a regular rewards credit card to use when you fuel up there or make other purchases. That way, you can earn double the rewards by using both cards when you check out.
