Wow, so I'm the stupidest person on earth.
Had a long night / morning Saturday night / Sunday morning, and was going down to visit my Grandma, a trip that takes us past a Gamecrazy. I stopped in and it was living up to its name's sake on that Sunday afternoon, it was packed and insane in there. I grabbed a used copy of Dead Rising and went to the register. I felt bad for the clerk, 10 years olds were constantly asking him specific details about PS2 YuGiOh games, et al.
Well, with a growing line behind me and a stressed out clerk the game rang up $50, not $25. I figured rather than ask about the price or be a jerk and be "Oh, I don't want a game for the price it was stickered at!" I'd just buy it, and swing by later to return it.
On the way home last night I had my wife grab the game from the back seat to see how many days I had to get it back to the store (it's about 20 minutes from our house). "All used game sales final," she read. Great.
Stupid sleep depravation ruining my judgment.
