This is an example of setting up a coupon that can only be used by customers who purchase a specific product on Shopify. A coupon is created that can only be used by a segment with a specified customer tag, and Flow is used to automatically assign the customer tag when delivery is completed.
Example of a coupon that can only be used by customers who purchase a specific product

[Setup Method 1] Create a customer segment with the "Shoes Purchased" tag

[Setup Method 2] Create a coupon that can only be used by customers in the "Shoes Purchased" segment

[Setup method 4] Create a flow that assigns a customer tag once the order has been shipped (after purchase, do not issue the tag immediately, but instead determine that the purchase has been confirmed).
