I got the latest KB Toys email newsletter, and it advertises Buy 2 Get 1 Free on all games excluding hardware & bundles.
I know KB probably has tons of crap, however its worth mentioning.
did it have a giant white 9.99 sticker on it? If so, its a front row game, view the thread below for all of them.

Make sure you have the employee price check them if they are still marked for the original price of $25...my walmart had them marked reg price, but rang up at the register for $7.
EB/GS has now stopped selling new GBA games, and in fact has converted all their left over new stock of GBA to used (just like Cube a few weeks ago). You might be able to pick up some seeled GBA games at used prices.
