Gary, I was in the PO the other day and asked the girl for an approx cost to send a figure to the states. It was more than twice the price of yours and would have been double boxed, it was AFA graded as well. She said it would be about £25, that was tracked and insured.
Mind you I didn't have the MOC boxed up, so we guessed at the weight, but either way I'd say £70 is a piss take.
