Eluxury.com is owned by LVMH. It's probably the only online site where you can be certain of a handbag's authenticity. Like Honeykiss1974 said, don't buy it from eBay. Too many bags there are faux, particularly popular ones such as Louis Vuitton or the Hermes Birkin.
As an aside, there are a ton of fake Birkins that those people have the nerve to sell for
boo-koo caiche. Losers.
