Can I show the converted price on the Checkout page?
The answer is no, unfortunately. At this point, we do not have the ability to show the converted prices using the customer's currency on the checkout page. Whatever currency the customer has used while shopping at your online store, prices will always be converted to your store's own currency when they reach the Checkout page.
However, you need not worry because we do have a workaround. On the cart page, you can let your customers know via a notification that the prices on the checkout will be in your store's currency. To do this, go to the Dashboard. Scroll down to the Cart Page Notification section and make sure the box is checked as shown below.
