Amazon's deal of the day is a doozy for fans of Guitar Hero: World Tour.  While the instrument bundles are normally around $190 - that gets you the drums, microphone, guitar and game - Amazon has them today only for $89.98!   This goes for every system: Xbox 360, PlayStation 3, PlayStation 2 and Wii!

Be sure to check out our review of the game if there's any doubt on your purchase!
