Why Add a Currency Message
A Currency Message is important to show if you let customers choose a custom currency. While the Custom Currencies add-on allows you to show prices in different currencies, customers are charged using the store currency and they need to know that for the sake of transparency.
The Currency Message can be changed in the store language settings.
