How can I tell if a Coach bag on eBay is authentic?

The best way to tell if a Coach bag on eBay is authentic is to find a seller with Excellent feedback who is listing a bag at a reasonable (ie, not too good to be true) price and offers a money-back guarantee if the bag is not authentic. Avoid bidding on bags which are too low priced or are from sellers outside of the United States. Also, an original picture in a listing (ie, someone took the photo of the bag in their own home) is more likely to indicate an authentic bag than a listing with a lifted photo.
