China has about the only items I buy on ebay anymore. Not great dollar stuff and the shipping is usually thrown in.

Ebay purchased Pitney Bowes the old maker of postage rate machines. So when am American vendor choose global shipping to Canada. He mails the package to them and then they go to work at adding additional charges. That the American vendor is not aware of. UPS set the record by adding 11 additional charges.

If an American vendor mentions Ebay's global shipping in his listing. In almost all cases I will pass it by. You get charged duty etc when if the vendor just mails the product to me direct. There usually is no other charges. Of course FedEx and UPS really add the charges on as well. Where USPS is fair. Some Americans vendors are all too aware of the scams. Not many though. Those I will deal with if I buy there again.
