How to add a custom attribute for "Cart Attribute" in Cart Price Rule condition?
I'm searching for a way to add a custom value in the cart attribute condition option for something like;
if "custom Subtotal+Discount" is >= X amount
get a free shipping
The subtotal option is not workable for me since when there's a discount in the order, the total will be less than the promotion.
for example if subtotal is over 100 get a free shipping, what happen now is when the subtotal is 150 but got a 100 discount and the total is 50. << this way the order got a free shipping which it shouldn't.
