Nah, I worked there on the weekends throughout college and you wouldn't believe the type of things we were forced to take back. We used to be told to be more accepting of the returns even if they were nasty. Every once in awhile I would get a little victory over some unscrupulous person trying to pass off a knock off as an expensive bag, but most of the time the managers would just slap a ticket on it and tell us to put it back out there.
Maybe it was a mistake. I talked to an employee there one time and apparantly, they get quite a few shady returns with people taking a price tag from something they bought there and attaching it to some junk that they want to get rid of.
