Hi ladies - I recently completed an auction for a Miu Miu bag (I am the seller of the item) and the buyer is now having doubts about whether or not the item they've won is authentic. As far as I know, this bag is authentic. I have no reason to doubt its authenticity - it was purchased through a completely legitimate shop (Bergdorf Goodman NYC), includes tags, and I have a second one of the bag in a slightly different colour and size, which I love and wear daily. Both bags are beautifully constructed and that, combined with the fact that they were bought from a reputable store, would convince me that they're definitely not fake. However the buyer of my bag said she got an e-mail from another Ebayer saying my bag was fake, and I don't see why someone would want to sabotage another person's auction - they would only want to help another Ebayer, probably. So now I'm wondering if I should be questioning the authenticity of the bag I've sold! I don't have a lot of experience with selling handbags, or the specific details of this particular Miu Miu (calf soft bow handbag), but I don't feel like I've done anything wrong here. I've been scouring the net and talking to other bag fiends (I work at a high-end store full of them) about problems with handbag authenticity and heard something about people buying authentic handbags, then returning fake ones for a refund (and therefore the authentic ones are kept). I don't know how likely that is, but if my bag is a fake, that's the only way it could have happened. I am a trustworthy person (yeah I know, anyone on the internet can say that, right? ), absolute abhor fake designer merchandise (and would hate to cheat anyone out of their money), and have maintained 100% feedback over the past few years. I listed my auction as being authentic because I had no reason to think otherwise, but apparently that is being questioned by others. The buyer is in the process of sending me an International money order from Canada, and I haven't sent the bag yet. What is the best process from here? I have told this person that if they can prove the bag is fake, I will happily refund their money (and would just expect they cover the shipping to return it to me), although I don't think it would come to that. But what if I've gotten hold of a fake through a reputable source? It sucks because Bergdorf Goodman is in New York and I'm in San Francisco, so I can't just head over there and demand my money back. This buyer also has a history of non-paying, which worries me somewhat. Anyway, thank you, ladies for any help/advice you could give.
