Not only does Amazon sell games for cheaper than most retail competition, but now they’ve launched a new service today, where they will buy back your used games!!

Amazon launched the service today (it’s in beta), and are currently accepting over 1500 titles, spread out over various platforms. Even better, is that shipping is free, so that extra profit won’t be offset.

As a bonus for trying Amazon’s new trade-in program, for the first two weeks of the beta, they’re offering 10% off a future purchase of any game or accessory in Amazon’s video games store!

I checked out the prices, and it seems that some of prices vary on the console. For instance, AC/DC Rockband tracks is $10 for Xbox 360 and $7 for PS3 while on the Wii its $11.  Interesting to see it varied like that, but hey it’s still more than Gamestop and Game Crazy.
