I think this is interesting, kinda frustrating and even a bit concerning to a degree...
I'm finding that many/most of these Chinese retailers, except for FT, are using WANB shipping agent. The WANB tracking is no good once it hits the the USA.
The package then goes to one of various US shipping agents/customs brokers who slap a USPS shipping label on it. But you never get that USPS tracking # from the chinese retailer.
When I figured this out, I still had a package I was waiting for from CVapor, so I emailed them and asked them for the USPS tracking # corresponding to the WANB tracking # (the USPS tracking label is generated by the US shipping agent well before it hits the USA). They actually did respond with the USPS tracking #.
I need to be able to see when packages are coming!
I guess YMMV as to whether a retailer will supply you the USPS tracking #, though.
I emailed Vapesourcing (who is also using WANB) to request the corresponding USPS #. Been days now, no response. I don't see me using them anymore.
And here's the kicker... it appears these WANB packages are never going through US customs as there is no customs label on any of my WANB packages. Just a USPS label with a WANB label underneath. The USPS tracking # (if you're lucky to get it) never shows that it entered US Customs.
I'm not sure what to think about all this.
