Creating a Promotion with Cart Custom Attributes and Product Attributes

Use Case: You want to offer registered shoppers a 20% discount when they purchase products made of platinum metal.

The system checks if the shopper is registered and if the product they added has the attribute of platinum.

Key Conditions:

• The cart must have the custom attribute. See Create Cart Custom Attribute API.
• The eligible product must have the attribute value of platinum. See Adding Templates to Products.

To set this up in the Promotions Builder:

1. In Commerce Manager, go to Merchandise > Promotions > Builder. Edit or create a new promotion.
2. Create a condition Cart Custom attribute that determines if your shoppers are registered when shopping. Set this value as true for anyone who has signed up for an account.
3. Create another condition Cart Items condition to ensure cart contains product with attribute value of platinum.
4. Set up an Item Discount in the Actions section as 20% off.
5. Setup promotion code if the promotion has Coupon-driven toggle ON (by default). See Creating promotion codes.
