The Gulf credit card will be a good option for you if you are going to fill up only at Gulf gas stations. However, you may not want to apply for this card if you have a habit of carrying a balance on your credit cards. The Gulf Visa card comes with 20.49% to 26.49% APR which can eat up rewards you earn if you do not pay off the card balance each month. This offer can easily be beaten by a 2% cash back offered on the Discover it® chrome up to $1,000 each quarter. Also you get unlimited 1% cash back on all other purchases. Plus Discover card comes with lower APR and a 14-month 0%% interest introductory period (when the introductory interest rate is over, the ongoing APR will apply).
