Dynamic Currency Conversion

Dynamic Currency Conversion (DCC) is a regulated service from Mastercard and Visa. It converts the price of a transaction from a merchant's local currency to the customer's billing currency in real time.

Note that when you use DCC with an order, you cannot split the order into multiple shipments.
