I'm trying to set up a coupon code that says "if cart total is $X, then make a certain product free, if it's in the cart".
I have the special product in it's own foxy category, and I have the coupon set up to only discount that category. That part is fine, except it's only watching the cart total for THAT category, not all categories. I need it to watch the total for all categories, and then apply the discount to that certain product category only.
Is there an established way to do this outside of coupon codes?
