If you've been waiting for a price drop to pick up Guitar Hero 3, Pure, Soul Calibur IV, Devil May Cry 4 or Ninja Gaiden: DS, you're in luck. This Sunday, Best Buy is kicking off another video games sale, this time with a pretty heavy selection of decent titles, all for just US$10 apiece. According to the forums, they're already started putting stickers on the games, too.
