Whoa... I missed something on this thread. A seller on ebay CAN have authentic LV... and they can sell you new LV. The problem is... you will not be getting a good deal because they have to mark stuff up to cover the cost of purchasing the bag themselves. In most cases, from my experience anyway, someone will buy a limited edition bag... keep it in the box... wait awhile until no more are available... then sell it on ebay for above retail because there will be buyers by this time willing to pay more. Otherwise, most authentic bags on ebay are used and are therefore marked down accordingly. None of these people would have a contract with LV. They are simply going to the store and buying a bag and then turning around and selling it (new or used).
I'm confused why people are arguing about this.
Oh, and BTW, this is a VERY good seller. I have heard wonderful thing about her stuff.
