Left 4 Dead 2 is releasing next week, and Amazon has a solid deal for you on the 360 version. You can pick the game up for $55 and you'll get $10 off future video game purchases. If you picked up any of their other deals recently, you probably already have some credit to burn!
You can even get the game on release date for only $5, or free if you are a Prime member. The PC version is available for $45.
