I am not too sure about that either but when old bags go out of season, the price gets knocked down that low!! Hard to believe huh? I was able to pick up a few bags I missed that way. So that low price isn't too ridiculous.
My sister-in-law told me that the bag was purchase on Ebay a couple of years ago on Ebay for around $600, it also came with cards (which we all know does not mean a darn thing)... I'll look at it over the weekend and use the Authentication thread to see if it is a fake or not. I really hope not, $600 for a fake would break her heart
