A friendly GameStop tipster just dropped what we're told is the game-sellers Black Friday sales catalog on us. The dozen-page circular is packed with borderline deals including Xbox 360 sales bundles, deep discounts on some games (.99 cents for Rock Band Track Pack Vol. 2 anyone?) and peripherals. Highlights that I noticed:DS and Wii The under $20 Wii games The free Nerf gun, with Nerf Blaster $30 for Guitar Hero on Tour PSP and PS3 Madden PSP Entertainment Pack or Ratchet and Clank Pack for $200 Guitar Hero Aerosmith for $30 Xbox 360 Several 360 bundles Left 4 Dead for $50 PC World of Warcraft Battle Chest for $20 What are you eyeing?
