If you’ve been waiting on picking up Guitar Hero: Warriors of Rock or DJ Hero 2, you’ll be able to save $10 on them at Wal-Mart between Saturday, February 12th and Friday, February 18th as a part of their Grammy sale. The sale applies to any version of the game, so take your pick! I guess that’s all there is to this news post. Wal-Mart’s neat right? Video-games.
