Like all things, the answer to this is dependent on many factors, including location, item distribution and pricing.  If you are located in the United States or Europe, Amazon is far and away the most popular online marketplace.  However, if you’re in Latin American, you’re more likely to find success with a top online marketplace like Mercado Libre.  Similarly, if you’re located in the APAC region, the more popular options include:  Alibaba. Rakuten. Taobao. TMall.
