do You have an idea how to create a discount via custom line item for a shipping cost? I found discount only for products (Add cart discounts) but I need also create a discount for shipping cost. I know, that I can use promotion for that, but the best option for me will be create a custom line item and add it to the cart processor. Is it possible?
