I'm in South Africa. So my first question is, any fellow South African's or people willing to ship to the RSA?
I've just done some checking and if a U.S. bowyer could keep bow+package weight under 3 lbs. the cost for U.S First Class Package International postage to S.A. would presently be $33.25.
If you go to 4 lbs the cost jumps to $57.25.
Other postal considerations:
"Import licenses are not required for bona fide gifts not exceeding R 200 (Rand) in value."
And the really discouraging part, I just found is that package length is limited to 24". I suppose a take-down bow with a length of say 47" might just make it. Could be a real challenge, but might be an interesting one.
Hope that helps!
