Did you find that they are more and more chinese on-line shops around us selling electronic products? product prices on these shops are only half of those on exclusive shops, and all goods are free shipping.you know what,an emergency charger for Iphone is only $1.99, i was just thinking that the courier fee for shipping it from china to USA should be more than $1.99..how could something like this happening?? it's a mare's nest? Has anyone bought stuff at these sites? Give me some suggestions please.
