I've seen some ridiculously high ones myself, but you obviously have me seriously beat in this department Jim ... unfortunately for you.
Makes you wonder how Jin keeps his shipping down as low as he does.
I would say Jin's packaging protocols are his form of "insurance" for international shipping!
I believe the government of China subsidies the postage for a lot of international dealers.
It would seem like some sellers in other countries tend to offer a low selling price and mark up the shipping and
handling to compensate.
