Today's deal is at Bestbuy.com and features both Rock Band 3 and Green Day: Rock Band for only $19.99. Now these games are software only so don't expect to get the whole kit. Not even a little guitar or microphone. But this is still a great deal. I was definitely hooked on Rock Band 3 for a while when a buddy of mine bought it a little while back and I always wanted to play Green Day but never got the chance. Until now that is. So as always, click the Rock Band 3 image to head to that deal and the Green Day image to head over to that deal.
