Navy Federal has a new credit card offering that might interest you. It is called the cashRewards card, and it offers a 1.0% cash rebate on purchases. (1.5% on total yearly purchases in excess of $10,000.) It appears that you have to request your cash rewards and you have to have a total rebate of at least $20 to redeem it. It has no annual fee, no balance transfer fees, and no cash advance fees. The interest rate on this account is variable.
I'm not choosing to switch my card to this one due the variable interest rate, but it may be a good choice for you if you never carry a balance.
Don't forget...Navy Federal membership is now available to all branches of the service, including National Guard and reserves, and DOD civilians. Plus, your family is eligible to join. So far, I've converted my mom and two of my three siblings, and they're all delighted with Navy Federal. I imagine you'd be delighted, too.
