Guitar Hero III: Legendary low price
Even if you're holding out for Guitar Hero: World Tour, or if you just have Guitar Hero: Aerosmith for some reason, 60 bucks for a copy of Guitar Hero III and a guitar is a nice deal. The Les Paul alone costs $60 from RedOctane's website, and it doesn't come with "Paint it Black."
The deal gets even more awesomer when combined with the current "buy one, get 20% off" Wii game deal. We aren't Toys R Us policy experts, and we don't want to guarantee that the store won't give you some kind of trouble if you try to double-dip deals, but you can probably get a cheap Guitar Hero and a second cheap game.
