Well, the idea is so "simple" I think that if a customer buys a free shipping product, and also a non free shipping product, the final shipping of both products is free. I'm testing this:http://docs.woothemes.com/document/hide-other-shipping-methods-when-free-shipping-is-available/
And with this function what I get is to disable other shipping rates when the free one is activated, I can't understand the logic...As I see, the logical part of this "problem" is disable other rates if both products are mixed in the final cart, and if the user buys a product with normal shipping rate let it the same (actually it simply disables the other shipping methods) Is there any way to do it? M I doing something wrong?
Thanks in advance
