I'm working on a new wholesale website, and recently hit a snag that's pretty detrimental to expanding my business. I'm trying to create an ordering site where stores can purchase my items wholesale. However, it is standard wholesale ordering practice to only allow purchases in certain quantity case packs. For example, if I sell one widget retail and I sell that same item wholesale, then I'd require stores to order in either quantities of 3, 5, or even a dozen. So when I create a new item with the wholesale price, I also need to set a restriction to minimum order quantities. i.e. multiples of 3, so the drop down menu when ordering would be restricted to showing 3, 6, 9, 12, etc. thus forcing the wholesaler to order in those multiples.
