The exchange rate you hear on the news or may follow on currency converter websites is the "Interbank Rate", used by financial institutions
to exchange currencies against one another in amounts of $1 million (U.S.) or more.
However, this is not the rate used for consumers purchasing in a foreign currency. There are also typical credit card rates,
significantly to the disadvantage of the purchaser compared to the Interbank Rate.
If you are thinking of paying the U.S. Dollar price and are ordering with a Canadian credit card, the charge to your card will reflect the current credit card exchange rate from CAD to USD. In addition, most Canadian credit cards charge an extra 2.5% fee to convert transactions to another currency.
