Postal cost in current situation

[Empty_of_Clouds]

I was wondering what people think of the current postal charges from the NZ to the US (the likely destination, as most members are from there). At the moment, with added surcharges due to the decrease in air traffic, and as far as I can tell, NZ Post is charging around NZ$20 (US$ 12.50) for a small parcel containing a single pen (estimated weight under 250g). It may be higher, I won't know until I can contact the Post Office.

Is this postal charge likely to be a sticking point for overseas buyers? (the cost is not dissimilar for other major countries)
