I have had some experience on Taobao and Tmall. Taobao is for C2C (customers to customers) while Tmall is b2c (business to customers). Tmall has better quality in general (the brands sell directly to customers). For Taobao, the quality varies greatly. For me, I always read the ratings and reviews, in particular negative reviews very carefully. If the percentage of negative reviews is high, I would avoid that product. So far, I have had good experience. I bought some really high quality goods at very low prices. Similar goods would cost a lot more on Amazon.
