I recently added the ability to ship Priority Mail International and Express Mail International to locations outside the USA. Unfortunately, the shipping portion of the web site is not quite as well developed as I would like. For small orders, I can ship in a small flat-rate box for around $13.45. That option doesn’t show up in the selection list, unfortunately; I’ll try to remedy that, but can’t say when it will be fixed.
If you pay with PayPal, it’s quite simple for me to adjust the shipping amount and issue a partial refund for the excess shipping charges. Otherwise, if you see shipping charges you think might be too high, please contact me. I am trying to get the shipping charges to accurately reflect the shipping cost and not penalize DX hams with extra costs.
