I received the Fidelity 529 college rewards credit card earlier this month. I think for parents setting up a 529 College Plan, this credit card offers a fantastic deal and it is one of the rare credit cards that gives you 2% back on practically anything you charge to the card. In addition, it also offers you online Bill Payment service which lets you pay many merchants including even your mortgage or electric bill, companies that traditionally do not accept credit cards. Although for these payments no reward points are earned, you can still benefit by enjoying the additional float on the money that you otherwise would have to pay earlier.
I just hope that MBNA would not pull the plug on this card after the recent merger with Bank of America.
