For an 1/43 you could get away with around 10 USD for shipping costs priority mail
but as you can see, for instance this seller charges already 12 USD inside the US (wich is way to much IMO, but probably he will send "fragile")... the only way to go is to "ask seller a question", because sadly most of them overchage or use packages wich are way to big!
BTW, also note that USPS website usually quotes wrong prices for international shippments (at least toward Switzerland).. many times it gave 200% the correct price..
Anyway Chaos, great find! I think I may bid on this!
