Add 3 price for woocommerce product add

Hello,

This isn’t possible to do in WooCommerce core. You need a multi-currency plugin.

WooThemes has a Currency Converter plugin available that will convert the currency that customers see automatically, but they will still checkout in your stores base currency.

There are other plugins available that will allow you to edit the price for multiple currencies and have the customer checkout in that currency such as: https://aelia.co/shop/currency-switcher-woocommerce/. Note that you need to make sure all of your extensions support multi-currency if you go this route.
