I have products A and B. Every product has a shipping cost
When A is added to cart and costs X in shipping, every subsequent product added to the cart should have reduced shipping costs. Can I do this out the box?
From the looks of it, this is not possible with core Magento (Buy X get Y free only works on one product) so i'd need to write a custom rule
If someone could point me in the right direction, that would be great
