The prices maybe cheap, but postage is '?50-?500' per item!
Never heard of them, personally, but i'd be slightly wary of any business that only has a Hotmail address as a contact detail, plus offers Western Union as top-line suggesed means of payment (though, to be fair, they do take Paypal and VISA).
Its a scam! There are hundreds of chinese websites like this. I found one that sold xbox 360s and ps3 and everything for very little. They accepted western union as payment. They replied to my emails and everything, but after a little research found loads of people was scammed by them. I found a website that had a list off all the websites that did this scam but i dont know what it is now. But Uk only. Dont be fooled by these chinese fakers.
