Just a little background check on this site. They've been in business for a little over 4 years now and their site seems quite legit (accepting safe payment methods) and filled with very expensive looking products/brands.
Just make sure to establish some sort of communication before you start ordering from them and if you do decide to buy from them try something small and not so expensive just to test the waters.
I couldn't find anything to vouch the authenticity of their products' brand names, so maybe it would also be wise to ask about this before you do your initial order.
Hope this helps somehow.. Cheerios!
