The Amazon Gaming Deal of the Day today is Guitar Hero III for $30 with free shipping. If you don’t want the bundle with the wireless guitar, this is about as cheap as it gets (new). You could probably save a few bucks by finding it used. Keep in mind, any DLC you buy for this game won’t work in the next Guitar Hero: Aerosmith game.
