Well here is my Gamestop story:
I went in to buy my brother the Borderlands GOTY edition during the sale they had a couple of weeks back. It was 19.99 for a new copy, and I noticed that they had copies with 2 disks meaning you could get all the DLC from a disk rather than using a download code via XBOX Live. I picked up a copy and walked over to the nerdy middle aged cashier. I said "I'd like to get the two disk version as my brother doesn't have the internet in his new apt". He said no problem, and handed me one of their 'like new, open' games. I asked if they had any sealed ones as it was a gift, and he said no all they had was 3 'new, open' copies. I just rolled my eyes and bought it.
Fast forward a couple of days, my brother opens it up (in front of me) and 1 fucking disk. Upon further inspection it says there is a DLC card inside, and there wasn't. No Borderlands DLC card and no Duke Nukem Forever demo code (no big loss there). We brought it back to the same fucking gamestop, same employee and he put up a fight about it being 'open' and can't exchange it. I threaten to call corporate and he goes in the back and magically finds a sealed copy with 2 disks.
Fuck gamestop.
