Promo code with custom shipping
We have a cart setup that has a delivery fee system for flower orders.
There is a session variable "FlowerFee" that carries the fee over to the checkout.
That all works fine. What the client wants to do is have a promo code that is entered will deduct the delivery fee.
Can I setup a discount that looks for the existance of the variable flowerfee and if it is present then MINUS that amount from the cart total?
