I find it odd that Price Rules have somehow changed. We have used them on Sales Receipts flawlessly for the past 5 years. We assigned a subset of clients to a group and applied the Price Rules to that subset of customers for their products and it has worked wonderful. So if Price Rules have been broken then how do I assign specific prices for my products to a subset of my clients without having to duplicate all my products with different prices? Price Rules did exactly that very, very well for a very long time.
