Just from one glance at their website I would run a mile. No wholesaler selling such high quality branded electronics would have such an unprofessional website without even an integrated cart system. Furthermore, western union should ring alarm bells coupled with the fact that they offer no telephone contact.
In Summary: It's a scam website.
If you must persue it: Ask to speak to them over the telephone and to use Escrow (
www.escrow.com) and I bet they will say it's not possible.
