Look for the Trustpass logo for each supplier that you are dealing with just so to verify that you are dealing with a legitimate vendor of Alibaba.

But most of the them offer their products in wholesale basis. There might be a few of them who will offer in retail though.

You have to register to be able to contact possible suppliers you are interested in. Registration is free but contacting suppliers is difficult if they don't know the language you are using. Just try to contact them through email as well as via the chat applet which is available with Alibaba.
