I'm trying to make a one time discount for each product of a certain type per customer. If the user buy a product he will have a discount on it, but he cannot have it a second time.
How can I do that.
So far I couldn't figure out how to limit it for the product itself. Maximum usage determines how many times a discount may be applied across all customers or to a single customer's orders, which in my case should be empty (unlimited).
Where is the setting to limit the number of use per product to 1?
Is it a rule I need to code?
