Definitely check the archives for this one. I think a lot of people have been burned from all of the carriers like UPS, Fed Ex, DHL, etc.... as far as customs fees. The only one that seems to work well is the US Postal Service, at least for sending stuff from the US to Canada -- I cannot remember if there was the same problem in your instance though. Check the archives and see what was talked about before -- I think the thread should be within the last two or three years on this board.
