I've been lucky on ebay, but I have to admit I did not know of Bonanzle until I found TPF. My last purchase on ebay was a purple patent Sabrina that I am in love with. I must admit that I research for a LONG time before I buy on ebay--other comparable listings to make sure the item I'm interested in looks authentic, coming here to the Authenticate This thread, looking at the sellers feedback carefully as well as the sellers current items for sale AND completed items. Also look at the return policy--although if you get a purse said to be genuine and you find it is not, you can enter a dispute through EBAY, not PAYPAL and get satisfaction for 'item not as described'. A lot of careful work and no guarantee but worth it to get something you really want.
