When orders are shipped over international borders the receiving country may charge an import tax (also called a customs fee or import duty). We have no control over when and how these taxes are charged. Some governments provide a calculator so you can estimate these fees before ordering, for example here is one from the Canadian government. If you can’t find an import duty calculator for your country you may want to contact your customs agency.
All transactions are billed in US Dollars (USD). Currency conversion will be performed automatically by the payment processor. Currency conversion rates fluctuate constantly, but you can estimate the conversion rate by using Google (example: “100 usd to cad”) or any number of online currency conversion calculators.
