The Chase PerfectCard gives you 6% cash back on gas purchases for the first 90 days and 3% cash back after that. All other purchases earn you a straight 1% cash back. All the rebates you earn are automatically credited to your account. There's no annual fee for the first year, but there is a $19 fee after that if you don't use your card at least 9 times. The flat cash back percentages (no tiered structure) as well as the 6% cash back on gas for the first 90 days make this a card that could save you a lot of money.


Citi Dividend Platinum Select Card is one of the best cash back cards out there. With no annual fee, you get 5% back on purchases at supermarkets, drugstores, and gas stations and 1% back on all other purchases. The only caveats: you can only "earn" $300 per year and you have to call and ask them to send you a check when you reach at least $50.


The Discover Platinum Gas Card is a great way to save on gas. Here's the deal with this card:

• No Annual Fee
• Earn up to 10% Cashback Bonus® award* on Gas Purchases
• Earn up to 2% Cashback Bonus® award* on your Other Purchases
• Earn up to 10% Cashback Bonus® award* on restaurant purchases 9/1-10/31!

You actually get 5% cash back on gas purchases and 1% on everything else. The 10% and 2% mentioned above refer to the fact that you can redeem your cash back for gift certificates that are worth twice as much as the amount you redeem them for. Or, if you prefer, they will send you a check or simply credit your account. Discover cashback bonus works on a tiered scale - the more you spend the higher you get back. You have to spend at least $3,000 in a year to get the full 1% cash back.
