I buy from many suppliers on Alibaba, but only from sellers that accept payment through PayPal. Alibaba's Trade Assurance Program only assures you of one thing, you will get ripped off. I have, over the years, asked PayPal to intervene with three different sellers on Alibaba that I have bought from and paid through PayPal. All three suppliers tried to rip me off one way or another, and each time my money was refunded to me by PayPal. No matter how good a deal seems from a Chinese Supplier, don't do business with them if they refuse to take PayPal. A honest supplier will take PayPal, they know they have to live up to the deal.
