I know there are a lot of great rewards cards out there, but when it comes to saving on gas which is REALLY the best? I drive about 45 miles everyday back and forth to work and I have an SUV. I've been spending way too much on gas every week and every little bit counts, so I would only be using the card strictly for gas. Any advice?

I am having no idea about it but if I got any information related to it I will tell you.

To maximize your payoff, do the math. Size up your own travel and spending habits, as well as the rebates, rewards and rules.
Years ago, credit card reward programs were simple: There werent any.
Then Discover came along with its cash-back offer, and airlines hooked up with banks to issue credit cards that earned frequent flier miles.
Today, consumers face a bewildering array of ways to earn, and spend, credit card rewards:
# A credit card can contribute to a retirement account, score theme-park tickets or knock thousands off the price of your next car.
# You can convert miles into hotel stays or restaurant meals -- or use them where you stay and eat to earn extra miles.
# Once you reach the stratosphere of spenders, you can use your rewards to design one-of-a-kind vacations and experiences, like a week at a French cooking school.
All this choice leads to inevitable second-guessing. Sure, youre getting rewards. But are you getting the most rewards possible? Do you have the best card, and are you taking the best advantage of it that you can?
