Let us know when they say they've shipped and if they provide tracking numbers.
Tracking numbers from China are valid from good vendors, don't mean anything from scammers. Here's the essence of a couple of posts I've made elsewhere.
[drop shipped from God-knows-where] ...nearly past the 30 day Ebay feedback window, I got a shipping confirmation in the style of a USPS tracking number. But # unknown at USPS. I finally traced that # to learning it was a Philippine Post number, but they showed 'no information'. Weeks later the item arrived with markings showing China Post (expected) overlaid by Malaysia Post (WTF??). Likely his use of a bogus Philippine Post tracking number was only to 'prove' to Ebay that he shipped timely.

I got a tracking number today for an Ebay flashlight from Hong Kong. I discovered this company [
ParcelsAp] will tell you which courier the seller uses and progress of the package.
My tracking number was a Yanwen number. Parcelsapp says they are an intermediary (similar to UPS) who collects parcels and takes them to China Post in bundles (maybe in full container loads?) A China Post tracking number is assigned to the package when they receive the container inventory but before they have possession. Then the parcel (container?) is handed to an airline or ocean shipper.
The Yanwen # will track progress of the parcel within China. Then the new China Post tracking number can be recognized by USPS and will show progress clear to the buyer's door if the higher-cost YANWEN Express option was chosen by the shipper.
A caution that I read elsewhere is that these tracking results will sometimes be posted by Yanwen or other intermediaries earlier than the actual progress of the parcel through the system. If the seller has chosen a reliable shipping handler, then its rare for a shipment to disappear. In particular the Chinese government works hard to make shipping reliable for exports and anything within their control should be reliable, if at times slow.

In this case with unreasonably cheap ebay prices, tracking numbers are likely imaginary. Or possibly valid numbers but tracing the shipment of a brochure or toy.
