Curcy is a plugin to extend WooCommerce to add multi currency support.
It’s a lightweight way to add multiple currencyies to your WooCommerce store.
I used it recently on a client projects and it works really really well, it’s a freemium plugin and at $34 for the pro version it is very reasonably priced.

Wrap Up
Although not my favourite way to add multiple currencies to a WooCommerce store, I much prefer the more through way of adding multiple languages and currencies with WPML, Curcy does the job and works really well, I recommend this plugin for a lightweight implementation of multiple currency support.
