Usually, most nations now have online services which simply need the destination, dimentions and weight entered and will give accurate rates for different types of service. Anyone that doesn't expect as a buyer to have to pay duties and taxes on foreign goods is living in a different world. Most sellers now put this disclaimer in their ads.
I live in a small rural community that basically only gets mail service. So, I'm handcuffed where getting parts delivered is concerned. Most people, even Americans, are not aware of the vastness of Canada and how far apart major cities can be. For example, I drive over an hour one way to hit major suppliers or make do with what I can find around my area. On line service by mail certainly has been a step up. I respect sellers rights to dictate where and how they send their goods but wish as a buyer that they would only realize the restrictions they place upon themselves by narrowing their delivery area. This is now a global marketplace and I just wish sellers would realize this fact. JIM
