The 5 dollar sale a few summers ago was legendary (since it was leaked a week early and we were the only ones who knew about it)
... but I probably made out better the next year when they added new games each month, and the older games went down to 1-2 bucks apiece... I remember making a trip out to a CC that never marked down games (although they were marked down in the system)... they had TONS of 2 dollar games there, so many I didnt get them all... spent about 80 bucks and came back with 2 big bags of goodies)... my local CC only had about 3-4 games, but this CC out of town was loaded... I do recall another CC in another city the same time that had alot too, lots of gba games
When Rhino was still in business with their 2 for one deal, many 9 dollar or less games from CC clearances still qualified at rhino, so I credit CC with helping me buy most of my 360 collection at an average of about 20 bucks apiece for new games
