Buy.com is running a promotional right now on Guitar Hero 5. Buy GH5 (either the game or the bundle) on any platform and you'll receive a code to redeem for Guitar Hero: Van Halen when it's released (up to a $60 value). The site says this is only through Buy.com so be forewarned. Seems like a pretty sweet deal. Get your inner rock star fix starting here:
