Hi there- I bought this "Authentic" Coach handbag on eBay, which I haven't paid for yet. I received an email from some other eBay member stating that the Coach bag I bought was a fake. Someone on this site confirmed that, but the seller wants to know how it was determined that this was a fake Coach handbag. She claims this bag was purchased for $400 and is adamant that it is a real Coach purse. Please help. See below. http://cgi.ebay.com/ws/eBayISAPI.dll...MEWA:IT&ih=002 Thank you so much.
