If Kate Spade is not even a handbag worth buying to begin with, what are you doing on a Kate Spade forum?? Just wonderin'...
If, as a buyer, you know your seller and have your head out of your butt, you can get some nice premium handbags at a great price. I have bought 2 absolutely authentic LV bags on eBay, both at a great price (<50% of retail). I checked out the seller, asked the authenticators here to look at them, and knew the eBay buyer protection plan would back me up. "Anything goes on the internet" does not mean someone can steal from you by selling a counterfeit.
BTW, I said last night that there are so many counterfeit
Prada and LV bags on the 'net in general, I'd be more likely to go to an actual designer boutique in a hoity toity mall than risk a seller I did not know.
