Thanks for the wonderful share!
As a local Chinese, i have some points personally.
1. I placed many orders on 1688.com. It's better you know how to compare with other suppliers. Many items are mis-title and mis-discriptions, just for the listing ranking. Not actual items. Need to check carefully.
2. For a Chinese, i always received the orders not as expected. DO NOT BELIEVE THE DESCRIPTION TOTALLY!!! Double check with the suppliers. If you do not know the language, it's not easy.
3. Return is a problem. I can return it quickly at lower cost, but when your orders shipped to oversea, and are not expected,cost much to return, for shipping US to CHINA is cost much than CHINA to US. And take long time. Many times, the shipping cost is much more than the items themselves. Better have someone or some company can do this for you.
4. Even the price is good there. But you get what you pay. Even have cheaper price at pingduoduo, which had IPO in USA. But i will definitely not buy anythings there.
