^Boots, please don't bid on this one!
There are just so many things about this auction that sets off alarm bells in my head.
First of all, SKU doesn't mean anything for a Chanel bag, what you need is a shot of the authenticity tag as well as the card, so that you know they correspond.
Also, the model number of the bag is blurred and that is unacceptable, the seller should be able to take a clear picture of the bag by using the "macro" function on his/her camera.
The seller has 0 feedback as well, I am not sure how comfortable you'll be putting that much money with a new seller.
The large vinyl cabas retailed for USD$995 and the x-large for USD$1225 - hope this helps!
