I ran into this a few times.... "I'm not comfortable shipping to Canada". It was a $100 item to be thrown in the mail????? I don't understand where the issue was. On the other hand, I have had a problem exporting when a customs broker was required. It was a large item going LTL freight. The buyer played stupid (couldn't understand English when it was convenient) and I did all of the customs broker work and got stiffed for $120. Maybe he will read this
