Brian, for pricing rules with price breaks, quantity discounts, pre-decorated products in a store, and products offered in the Designer for decoration, there are no limits to the numbers that can be entered, zero to infinity. Is there a specific issue you are running into, please provide details or reach out to your CSM? I have attached screen captures for pricing rules, quantity discounts, pre-decorated products, and blank products in the Designer, showcasing the areas where you set quantities. Maybe I am misunderstanding the question?
