THIS is the eBay killer. I am based in China and use this website for almost everything... from buying groceries to top-up codes for my mobile phones. It's incredibly safe, fast, and the vendors on this site have an internal system (called AliWangWang) for customer service. Again, it's super safe... but YOU NEED TO SPEAK CHINESE or no chances to use it. Taobao also offers a "trusted" platform for business called Tmall.com, which is something like a walled Taobao for 100% legit businesses. For example I constantly buy a lot of shoes from this shop on Tmall called Tstage.cn and through AliWangWang I can ask details about styles and sizes, or return something. And returns on Taobao are almost always free and included in the service. I wish a marketplace like Taobao existed in the West. I will be lost the time I return home from China!
