I use this site for my overseas tracking numbers

Well, Nick I ordered from same seller, and recieved same generic response. Mine, however, showed posted within 4 days, and movement through China to export location as expected.
Dealing with many countries, I know I've had experiences where items sit in customs, or export centers, for days or weeks. Tracking shows export country or destination country depending on which end it is sitting in.
Fingers crossed this isnt a banggood type deal. If so, as you said, paypal is good for refunds.
