Selling to Overseas Customers?

Since I marked my items as being available anywhere, a good portion of my orders have been outside the US. I have been a little surprised by this. Is that typical of your business? This has only been a short while but 4 instruments out of 7 have been for folks in Japan, Germany, and Wales.

Shipping has gone smoothly so far for me, but I see a lot of folks are resistant to shipping overseas. Have you had issues specifically related to shipping to other countries?
