i;m no expert at all but in looking for Burberry on e-bay, came across these items which look incredibly fake and/or ridiculous to me (someone correct me if i'm wrong!). the seller feedback (or lack of it) also raises a doubt. or, sometime's its not the item itself but the incoherent/unusual English in the seller's comments that gives it away ("You must to have it!" "Bid with confident!"). LOL. I also love it how often the best thing the seller can say about it is that "it comes from a smoke-free home."
You know what's more amazing? When I put up my bags for sale, i am constantly prompted and reminde that eBay reviews all such listings for authenticity. That is obviously such a farce seeing the sheer number of things that fall through the cracks!
