Wonder if there is any big marketplace like Alibaba or DHGate that can be used with Bitcoin?
I know DHGate is very peer to peer but not sure if bitcoin is allowed.
Something like alibaba or aliexpress can be shopawl (I haven't tested it yet) which is third party website which accepts bitcoin.
Here is their thread here in forum, ask there for any additional information
