I found a bag that I really like on Ebay. The seller has a feedback rating of 100% but with only 3 feedbacks. I posted in the Authentication thread. The picture of the tag isn't clear, but one person said she thought it looks good. I called Gucci and the serial numbers match the style of bag. She said that she will email me her statement with the info of purchase date, place and amt paid with her Amex card. The purse is in fabulous condition. She is selling it to purchase another purse. I have sold numerous authentic handbags on Ebay, but I've never purchased one. What would you do?
