I misunderstood and I apologize. I would never advocate someone returning good merchandise that they used but are simply bored of or regret. That's no better than using Nordstrom as a free clothing rental for events.
Absolutely.
I think it's disgusting to return used stuff just because people regret it or don't need it anymore. I know some folks who return stuff after using it multiple times and even WASHING it a couple of times, which is simply a gross thing to do. I absolutely abhor such practices and no store should brook such returns. In fact, stores should ban such customers. Sorry if that sounds harsh, but you have the separate the wheat from the chaff.
Like I've said, I've in the past received stuff which looked slightly used and it didn't bother me much, but I'd NEVER accept something which looks awful and overused.
