Mostly, it’s eBay. Except in China, where it’s Alibaba. The online auction space, where every day millions of people send hundreds of millions of dollars to people they don’t know, for goods they’ve never seen. eBay alone has 203 million users, and processes an estimated US$50 billion worth of transactions annually. Welcome to the global marketplace. Sell your products directly (a quarter of the products sold on eBay are brand new) – or simply market them to the mind-boggling numbers of visitors attracted to these buying and selling centers.
