Hi Cilla9 - interesting web site. My gut feeling is that since none of the Chloe afficionados talk about shopping from that site it couldn't possibly be an honest source, otherwise they wouldn't be purchasing from LVR in Italy with all its hassles to get a discount, or going without their Chloes when there are still legit ones on the market.
They charge a 10% restocking fee + $9.99 for all returns, so even if you return something they still make money off of you. They ARE legit with Better Business Bureau if you check that, but they have had a few claims regarding refunds - but it doesn't detail authenticity issues.
I just emailed them to ask questions about how they get their stock and how they process authenticity issues - how you have to prove it and if you don't get charged the 10% etc. We'll see what they say and I'll report back...
