Looking at all angles, everything seems to be right - they accept secure payment methods, the contact details they publish in the site matches with the record at whois (Round Rock, TX) and that the website has been around fairly above two years in existence, created July of 2007.
However, there have been comments from other forums online you may want to read on, and it's mostly about where they source their products from - Link hidden: Login to view
Hope this helps. :) Would you mind uploading a profile picture so we can see your friendly face? Thanks!
