US hams refuse to deal with their Canadian fellows

Why do American Hams refuse to deal with their Canadian counterparts? I have recently tried to purchase several items from the QRZ-COM lists and have been advised by the seller that he/she does not ship beyond the CONUS. I believe this is due to ignorance in how to export the item. You have only to advise the US postal Service &/or Courier what the package contains and value thereof. Sure the cost is somewhat greater but usually the purchaser pays the shipping. Payment is made in US$ usually by Postal money order or a bank International money order. What in the world is the big problem in dealing with your Canadian friends?????
