My company is currently running a Magento V1 store that sells to the USA & Canada. We have two currencies setup for the store which of course are USD and CDN. The USD is the primary currency for the store. When a Canadian customer goes to checkout even after they have selected the CDN currency from the navbar it will charge the sale in USD to their credit card or paypal. During checkout it will give a real time currency exchange from US to CDN but in the end a USD charge will appear on the customers Canadian credit card. The is causing some issues with certain clients whose financial institutions will add a currency exchange fee onto their transaction. Are there any workarounds for this? either in the settings or through a plugin?
