Here are the steps needed to create the discount from the rule page:

Step 1: Configure the rule

You should set the trigger, action, schedule and targeting on the rule to do what you want the rule to do.

Step 2: Set how you want to discount the action product

The most robust method to discount the action product is to use an EG Automatic discount. However, the other two methods are good alternatives should you want to use that instead, as you can only create a maximum of 25 app discounts, which EG utilises to make the EG automatic discount.

In the Discounts section of the rule page, select the discounting method you want to choose and click 'Create new'.

Clicking on 'Create new' opens a modal where you can configure the discount to work with the rule, you can choose between discounting the action product by a fixed percentage (any value between 1 and 99%) or make it completely free. You can also configure the other discounts you want this discount to combine with, note you will also need to ensure you configure the other discount(s) combination settings to make it work with this EG discount. Once you've finished configuring the modal, click 'Continue'.

Step 3: Save the rule

Confirm this works to how you initially planned by testing on your store.

💡 Notes

Rules that use products or collections with selling plans can't use a discount since Shopify does not support this.

This feature may not work on old rules. If you can't see the create buttons in the Discounts section, you should recreate the rule and then create the discount from the new rule.

When a discount is set up using EG for a rule using a cart value trigger, EG creates a private collection (it is not published to your storefront - your customers will not see this collection) in the backend of your store containing all products in the store. You should not delete this collection - it is used by the discount.
