Be cautious buying sunglasses from them.  I just bought 3 pairs, cauitous purchase and I am glad I did it that way.  They sent me the glasses and they were complete junk.  2 of the 3 pair had lenses which had fallen out of the frames the cloths looked used and dirty and the hard cases were crap.  after dropping $150 including shipping they offere to refund me $30.  It deosn't even cover the cost of the 2 damaged glasses!!!!!!
Stick with authentic, it will keep you out of trouble as well.
