With gas prices increasing again what credit cards are the best to use for discounts at gas stations? Hess gas stations offer a credit card (Chase) that gives a 10% discount for 6 months then a 5% discount after that for all gas purchases at Hess gas stations. Wawa offers the same deal for gas purchases at Wawa gas stations. Both offer 1% discount on all other purchases and gas purchases at other gas stations. Do any credit cards offer a similar discount regardless of which gas station you use, if I went to Hess, Wawa, Sunoco, etc. I would still get at least a 5% discount with the same credit card?
