I tried selling a purse I got last year from the Coach factory store on eBay and someone reported it as fake and my auction was yanked. How could this happen? I have no idea how to tell if the bag is authentic (I'm reading through some threads to try and figure it out) - I just assumed that buying it from a Coach factory store meant that it was authentic. Can you all tell me what you think in terms of authenticity? If it is in fact not authentic, what should I do? Take it to a Coach store? Unfortunately I've had this bag for over a year and don't think I have the receipt anymore. If the bag ends of being a fake, I'm going to be angry & embarrassed for accidentally posting a fake on eBay.
