Use Case: You want to offer a discounted price for a particular product using the promotion code, rather than discounting the price for all shoppers in Price Books.

To set this up in the Promotions Builder:

1. Specify the cart item to target the specific product. To do this, see Cart Item condition.
2. Create an Item Discount in the Actions section and choose a fixed price.
3. Specify the quantity required to avail the discounted price for the item.

By implementing this, shoppers can use a promotion code to purchase the product at a reduced price, offering targeted discounts without affecting all shoppers in Price Books.
