Ebay has a really good area with ways you can spot fake Dooney and Bourke, Juicy Couture, etc..... and this is the link to the Juicy COuture info:

As I was reading it said that Juicy Courture NEVER wraps anything in plastic only tissue! That is one of the ways to tell a knock off from a real one.
I think the ones on the site you found are knock-offs and they are scheming! I have looked through that whole site and there is NOTHING small print or large saying those bags are not real! I wouldnt recommend buying from them!
