Earn $25 Credit On Your Bank of America MasterCard YMMV (Exp. June 30, 2011)
Make purchases of $250 or more with your eligible Bank of America MasterCard between the time you register for the promotion and June 30, 2011, and receive a $25 statement credit. If you only spend the required $250 minimum, that’s 10% off.

Make sure your account is eligible for the promotion. If you didn’t receive a notice with a registration code in the mail, you can call 800-732-9194 to check or go to bankofamerica.com/easyrewards , click “Don’t Have One?” and enter your name, zip code, and last four digits of your credit card. If that card is eligible for a promotion, it’ll be listed on the next screen.

People are reporting that they've been getting a different promotion so it's definitely card dependent (mine's a BofA Preferred MasterCard). I just tried my World MC and got something different, a mystery promotion?! Could be a fun game to play with your BofA cards...

And for those of you who are running a promotional low-interest balance on your card, you can still make the promo work for you; just make sure to pay your monthly minimum payment plus the new $250 charges (or whatever amount the new charges are).

Fine Print
Your card must be eligible for the promotion and you must register the card.
Make purchases of $250 or more with your eligible credit card (purchases must post between the registration date and June 30, 2011).
The $250 excludes credits, returns and adjustments, and fees, interest charges, and unathorized/fraudulent charges don’t count towards the minimum.
Credit will appear 10-12 weeks after closing date of offer.
Be sure to pay your monthly minimum payment, even when you receive the $25 statement credit.
