I need to set up two category discounts, as follows:
(so: for all products in that category only, I want to give 15% off the price of each unit if they buy 10 or more, 15% off it they buy 15 or more, and an additional flat discount of $80 if they buy 20 or more)
The form field in the category page doesn't let me paste that configuration in. It apparently only allows one discount.
How can I do this?
