The product discount customization can be applied individually to products, specifically to products offered in checkout components like upsells and cross sells, or both.

This guide will show you how to set up a product discount specifically for checkout components.

Create the product discount

Select the product discount customization and make sure to select the variants to apply it to, along with the discount message, discount value. The area it applies to should be set to Checkout components only**.**

Create the metafield definition

If you are creating a product discount applicable only to the Cart area then this step is not required.

Navigate to the Custom data section in your settings, and select Variants:

Within the Metafields without a definition you should see the checkout_buddy.markings metafield. Click Add definition.
