GameCrazy Living Up To Their Name: Raising Used Game Prices

I stopped in to my local GameCrazy (or is it Game Crazy?) to see if I could pick up a decent used game. I swear that their used game prices jumped by $5 to $10 per title. I picked up Timeshift for $9.99 a few months back, and they were selling it for $17.99 yesterday. I’ve never seen used game prices go up at GameCrazy (or anywhere else for that matter).
