A cart promotion acts like a smart assistant at checkout. It watches what a customer adds to the basket. When the basket matches the rule you set, the promotion applies a discount or adds a free item. If they meet the rule, like buying three items, they get the reward instantly.

How does cart promotion work

A cart promotion performs three actions in real time:

Scan the cart. It reviews the spend amount, item count, brands, or even the time of day.
Check the rules. It compares the basket with the conditions you have defined.
- “Did the customer spend more than $100?”
- “Did the customer buy two shampoos?”
Apply the reward. It updates the bill.
- Money off
- Free item
- Bundle price

How to set up cart promotion

Brand setup

A marketing manager defines the logic in the system.

Condition: “If the customer buys two shirts…”
Benefit: “…give 20% off the second shirt.”
Limits: “…apply once per customer, only in New York stores.”

Customer experience

The customer adds items to the cart and proceeds to checkout. The system checks the rules and applies the benefit. A line item appears such as “Cart promo: -$15.00,” and the customer pays the reduced amount.

How cart promotion differs from other promotions
