I know I haven't. :)
But seriously, they're a relatively new site, having been created just last June 2009. Also its kind of fishy seeing that they are a Chinese site and offering branded electronics. If you haven't noticed, it's now like a mantra on the forum - 'Do not expect to buy anything authentic and branded from China!'
Reading through their site, I would presume that their method of payment is wire transfer. Where you deposit 50% and they promise to ship out your order upon receipt of payment. (Zero assurance on your part here)
We have always advised our members to not easily trust suppliers using a free email account (this one's using hotmail.com). Legit suppliers will oftentimes have domain based email adds.
Hope this helps. Cheers :)
