Amazon is offering a half decent pre-order offer right now. Pre-order select titles and receive a gaming credit to your account within 2 business days after your game ships in the amount of $10! Choose from titles such as Vanguish, Assasins Creed and NBA. Click here to check out this offer. I’m not sure how long this offer is valid for but it does state limited time only. I can’t suggest which titles to pre order though because I’m not much of a gamer.
