I just started selling on eBay and just sold my second bag today-however before the auction closed I got a question from a bidder. She was asking me questions about the bag being authentic, which of course I understand. But she wanted me to fax her my receipt(which is from Neiman's and was posted in the auction)Isn't that a rather nervy request? She says she wanted it to see if it was authentic. I declined to do so (politely) and I ended up selling to a super nice ebayer who paid immediately. How would you guys have handled that request? Thanks!
