I pre-ordered it from EBGames.com about a week after I heard about the deal and received it in the mail in early February. I believe that was the first week it was available. This thread may also help.
I have a friend who works at Target, and they are handing out copies if you pre-order the game and put down $15.00.

If you're still struggling with this and have held onto the game, maybe the patch they've just released will help? There's nothing specifically mentioning your problem, but maybe it's part of the memory leak issue?
