Magento Go lets you configure your store to accept currencies that are used in more than two hundred countries around the world.
In addition to setting your accepted currencies, you can also manage currency rates for your store. If you accept payment in multiple currencies, make sure to monitor the currency rate settings, because any fluctuation can affect your profit margin. Currency rates can be set manually, or imported into your store. Currency symbols are used throughout your store, and appear in product prices and sales documents such as orders and invoices.
Before you can set currency rates, you must specify which currencies you accept, and which currency is used to display prices in your store. You can customize the currency symbols as needed, and also set the display of prices for each store view.
