The battle is truly on for your fall gaming dollar as Amazon has unleashed a killer deal for gamers. While normally they offer a $5 or $10 credit for preordering titles through their site, this deal trumps them all.
When you spend $80 on qualifying games, they are going to give you $40 in credit towards future game purchases. The list of eligible video games is about 600 titles deep, and titles like Uncharted 2, Borderlands, Marvel Ultimate Alliance 2, Operation Flashpoint 2, and The Beatles: Rock Band are all on the list.
