We sell milk in glass bottles, which carry a $2 discount. Since the customer will get back the full $2, we need to exclude the bottle deposits from discounts. We used to do this by making the bottle a separate item, but our cashiers would too frequently not remember to add the deposits, so now it's a modifier. However, we can't remove a discount just from the modifier, and not from the milk itself. Am I missing something? Can this feature please be added?
