Craft Commerce - Free Shipping Field So there is this field called «Free Shipping» for each product.



But I can't find anything about this in the docs. I found out that I trigger it with 


  product.freeShipping


But when activated it has no effect on shipping costs whatsoever.

What's the idea behind this thing, and how do I activate it?
(I'm fiddling around in the standard templates)?

I thought about creating a Free Shipping Category and then activate it via conditional. Or what's the idea about this?
The free shipping flag on individual products stops costs being calculated by any shipping rule that is a per item rate or weight rate.
