This is a good attempt to look authentic, and it'll fool people easily so be careful. Fake verisign badge on the front, fake testimonials in the back, enough said. There are hundreds, if not thousands, of sites selling "100% Authentic" handbags and sunglasses. I shouldn''t think it's even possible to manufacture as many bags as these sites claim to stock, and if it were, they wouldn't be exclusive any more because everyone would have one.
In my experience of reading and talking to people, to date, the only safe way to get a replica bag of genuinely high quality is to go to China and look for one there. Anything bought online is unseen and untouched by you, so you have no idea at all what you are about to purchase. Never, ever trust a photograph, as these are commonly of the real item and 'borrowed' from an official retailer. And never expect to get your money back.
If you want the real thing, with a guarantee and somewhere legitimate to return it to should you need to, don't expect to get it at a third or less of the retail price. Some of these "authentic" bags sell for as little as a fifth or eighth of the price you would normally expect to pay. Don't be fooled. Offering something for nothing is the oldest con trick in the book.
By the way I also took a look at their Facebook page and found that some of the entries led to sites classified as malware or porn. Explore at your own risk.
