Taobao is a C2C model, which means they only provide a platform, and the real sellers are individuals. You must check the reputation and payment method. For large products, you must ask about warranty and other after-sales issues to avoid unexpected disputes after the transaction. In China's C2C market, Taobao's competitor eBay appears to be more wealthy.

In March 2002, eBay invested 30 million US dollars in Eachnet to establish eBay Eachnet; in July 2003, eBay invested another 150 million US dollars in eBay Eachnet.

The sources of charges for C2C websites mainly include transaction service fees (including product registration fees, transaction fees, reserve price setting fees, pre-sale setting fees, additional transaction fees, security fees, and online store fees), special service fees (including font function fees, image function fees, and recommendation function fees), and value-added service fees (information publishing fees, auxiliary information fees)
