<VERY BAD COMPANY> I should have read these negative reviews before placing my orders from 86daigou.com. My mistake. They have the following negative issues : 1. A lot of hidden costs: they show you the low price for the products. Once a product has been ordered, they will ask you more money for packing cost, shipping cost, insurance cost for shipping. If you don't ship soon enough, they will ask you to pay warehouse storage charge. There is no way for you to find out the shipping cost beforehand. 2. Very bad customer service : they replied to your email promptly but make things very difficult for you. I sent 9 emails to ask for refund after finding out there are so much hidden cost involved. They use all kinds of reasons to delay the whole refund process. At the end, they tell you order can't be refunded anymore due to exceeded the refund time limit. So, you advise you to pay the shipping(very expensive), so they can deliver the item. 3. DISHONEST REFUND SYSTEM : On their website, they show how they can refund you if you are not happy with the product. But, the fact is the refund $ will be sitting in your account and not paying you back cash. It's another painful process to request for drawing out this refund $ from your account. So, at the end. I ask them to keep the products and the money. Not to contact me anymore to ask for warehouse fee everyday. My advise : NEVER USE THEM AT ALL.
