I have a question that I hope y'all can answer - I don't want to install this mod becuase I'm not sure if it can do what I want it to do. Here's what I need: I have two broad product categories (patterns and yarn) For the patterns, when wholesale customers order between 1-30, the get 40% off retail. If the order 31+, they get 45% off retail. For yarn, if they order 1-50, they get 30% off retail. For 51+ they get 35% off retail. Can this mod set up that sort of pricing structure?
