These days, with customers shopping online from around the world, 24/7, making sure you embrace the global market is very important. Being able to switch between currencies is an integral feature for your customers experience.
However, if a multiple currency dropdown selector is shown as an option on the storefront, this offers reassurance that their needs will be met.
Customers can then see all product pricing in a familiar currency and remain on your store to complete the purchase.
Simply tick or untick this option to show your currency picker in your site footer.
To add a currency, go to your payment settings in Shopify admin.
