I have bought a number of things from them. It started with shoes -- a couple of pairs of Paciotti, which were perfectly authentic. Then, I purchased a pair of YSL heels. Also authentic.
A few months ago, I sucked it up and purchased a Fendi baugette from them. It took a bit of time to get to me, and I was very very anxious. I did get the item and it was authentic, but the anxiety was too much for the bargain.
I can't say anything for the other items they sell, but if you've got a good heart, you may take the risk for the bargain.
