Deal extreme online store, please help.

Hi all. please is there anyone who has purchased from this store: www.dealextreme.com I've looked at their website and I have seen items for apple products such as keyboards, cases, batteries, chargers, cables etc. Since the prices for some things are quite low my question is do you think it is worth purchasing stuff for apple from there. Charging cables are really cheap there but I have worries about quality. I really do not want my Iphone to be damaged plugging cheap cable to it. Another thing that sounds good to me is the fact that shipping is free, no matter where in the world you are. The store is in China I think. What do you think about all that was written above? Is there a chance that cheap cables might damage iphone? Looking forward to hearing your opinions. Thank you in advance for your help.
