As we confirmed yesterday, Call of Duty: Modern Warfare 3 is now available for pre-order pretty much everywhere by now, and for those GameStop PowerUp Rewards members you likely received an Email making you aware of this fact.

In addition, if you go into GameStop and pre-order Modern Warfare 3 before May 20th, you will get a special double sided Modern Warfare 3 poster for doing so. The promotion runs till May 20th or until supplies of the poster are exhausted.

From what our GameStoppers tell us, the double-sided Modern Warfare 3 poster is an additional pre-order bonus for placing your pre-order now, and is on top of any additional pre-order bonuses that may be offered.
