Good plugin, very dynamic

Not all currency-switching plugins allow you to not auto-generate converted prices, and enter them manually.

This plugin handles that perfectly, even for variable products. And gives you the option to set specific formatting for each currency (like the default WooCommerce settings do).

From a developers point of view there is no super clear readme (or at least that I found) to integrate this in any way other than WP shortcodes. But after a quick look through the plugin source files it’s not too hard to figure it out.
