I'm having some trouble setting up a quantity discount. I have a product that comes in two sizes, and each has their own color options. I have each listed as its own product within their category, with drop down menus for color choice on each. I have a quantity discount of 5% off for purchasing two or more of these items, and want people to be able to mix and match sizes. I downloaded Quantity Discount 1.6 so I could do a category wide discount. But when I add the products to the cart, no discount is given.
How do I fix this?
