I searched a lot and i didn't find a way to to it. I need to create a coupon code that when it's applied gives a 100% discount based on Shipping Price selected.
I don't want to change the price of the shipping to $0. I want to give a discount in the same price of selected shipping method.
Example of Shopping Cart:
Products = $100 Shipping = $15 Discount (COUPON FREESHIPPING) = -$15 Final Price = $100
That way i can control how much the company spends with free shipping.
How can i do that ?
