Hi! I recently won this bag on eBay and it seems like a really good deal. The bag is used, so obviously it wouldn't be 1500-2000, but I'm wondering if maybe it is a used fake? Can anyone help me? http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=150107026043&ssPageName=ADME:B:EF:US:2 Thanks so much!
