Thanks for the tip! I am anti Ebay at the moment, but it is good to know.
Regarding authenticity, I contacted Ann's Fabulous Finds (the website selling the bag) and they have guaranteed that the bag is authentic.
Many tPFers have used AFF and they have glowing positive reviews so I am confident in purchasing from them.
I don't think that I am going to get this bag, so it is up for grabs!
