bundle-rate-addon-for-woocommerce-shipping-pro

I've also written in the support section. I think this is a very nice add-on to WooCommerce Shipping Pro, but lacking some basic functionality. With this plugin you can, with just 1 product A, order 100 product B and you will only be charged the shipping for product A. I think it would be more 'real-world' if you can have 1 product B shipped for free, if you have 1 product A, or 2 product B with 2 product A, and so on. At the moment, that functionality is lacking, and unfortunately the developers seem to be unwilling to include this anytime soon.
