While browsing LV (and alleged LV) items on eBay, I'm seeing this on quite a few auctions. A copy is offered as part of authenticity "proof." Why would a seller who is ostensibly auctioning her own items give a copy of the receipt? Why not the original, what use would she still have for it? Offering me a copy of the receipt does not reassure me the way an original would (and even then, I realize that she could be giving me a receipt for a different item). I click right off such auctions, but maybe there's something I'm missing?
