Free Shipping Per Product for WooCommerce

It works!

Just needed to offer free shipping on a single product but if it was bundled with products that required shipping the free shipping option needed to be removed and this plugin did just that. Very simple to use.

Works well for my needs.

A simple way to set free shipping for certain products.
