At one point I had a Monedeo ring shipped over! Not sure what type of shiping it was. It just had a a bunch of stamps on it.
Also remember the Huge Bonnet Lifter GB I think there is another going on right now. To my knowledge I didn't pay any sort of tax (Other than local) and they shipped directly from Europe. It also came the same way, stamps al over it.
If I had to guess it was probably just individual mail.
Hope that helps
