I was originally turned away because I purchased from BB, but they eventually did a swap without too much hassle. I just told them BB refuses to help me, which was true.
The replacement they offered had a very minute scratch on it. It wasn't a big deal, and I had planned on taking it anyways, but since I was there I asked if I could see another one. The genius said yes, but double checked with his manager that said no--that it was too minor. I agree, it is really minor. I even had trouble finding it today.
