We sell jewelry and need help making a discount code that applies to a custom bracelet stack. Basically I want the customer to be able to add 3, 5, or 7 individual bracelets to a cart & use a discount code that would be a specific % off those items. This code would not apply to our bracelet stack items (premade stacks that are already discounted) nor would it apply to any item that isn’t a bracelet. Can someone help me?
