I usually fuel at Wawa gas stations as they are closest to my house. What is the most appropriate credit card for me? Is a Wawa credit card ok?

A Wawa Credit Card may seem like the only option, but it most certainly is not. A Wawa credit card will give you 25¢ per gallon for the first two months and 5¢ per gallon after that. While it may seem like good rewards, there's also a pitfall - you can use this card at Wawa gas stations only. If you are not sure that you are going to fuel only at Wawa and consider other gas station as well, this rule will only limit you. Try applying for general cash back cards that are just applicable to gas purchases at Wawa and anywhere else.
