I am thinking about selling my LV Speedy on Ebay (although I am terrified by all the scammers out there). Anyways, I was thinking of sending the original receipt with the bag to insure bidders it is authentic. Would this be a bad idea? Should I just include the picture in the auction and not send it? Also will a security tag help me for with the switch/bait scam? I just don't know which way is the best way to do it. Thanks!
