Advice to US international shippers: When shipping to Canada, UPS is the worst. They charge an arm and a leg to process the paperwork (often to the point where their brokerage fees outsize the actual duties and taxes owed), and even after I told them multiple times to use my own customs broker they seemed to "forget" or play games like delaying release of the needed paperwork. USPS is most reasonable, Purolator is OK, FedEx is still expensive but marginally better.
