I've a cart rule that sets "free shipping" under certain conditions. The rule works and free shipping gets applied as expected.
Now I must also retrieve and display the shipping cost as it would have been if no "free shipping" was applied. The purpose is to display a "you're saving XX € thanks to free shipping".
I'm using Magento ver. 18.104.22.168, the regular shipping price is calculated by "Premium MatrixRate".
I usually would post some code for "what I've tried", but this time I'm completely lost here...
