Add small text beneath price for non-default currencies

Hi Rosy,
In Checkout I’m forcing payments in my default currency EUR. So option where in Checkout it says like “( YOU WILL BE BILLED: €80,00 ) DKK594,88”.

I can not 100% accurately estimate the price PayPal will charge a customer in the customers local currency when the customer pays €80.
So on the Product page if the selected currencly is not the default EUR then just beneath the DKK594,88 price I would like to add a small text in red color with similar information saying “Approximate price (you will be billed: €80,00)”.

Similarly on the Cart page if the selected currency is not EUR I would like a small red text beneath the TOTAL saying “Approximate total (you will be billed: €80,00)”. And for the other price fields Price, Subtotal and Shipping like in the Checkout the DKK price preceeded by the price in EUR also in red color. E.g. Subtotal saying “(€80,00) DKK594,88”.

Are you able to assist me with some hooks/filters doing this which I can put into my child themes functions.php ?

Unless of course you want to add this to the plugin as a configurable option also benefitting your other customers 😉

Also the current message in Checkout I would suggest to show beneath the TOTAL in small red text saying “Approximate total (you will be billed: €80,00)” instead of the current “( YOU WILL BE BILLED: €80,00 ) DKK594,88” where the red message comes before the DKK price (a lot of text in one row which doesn’t look nice on smaller screens).

Best Regards,
Kristian
