In Flows (experiences), You can now create Dynamic Discounts tailored to specific Products or Collections within Shopify. Previously, Dynamic Discounts were only applicable to the entire order.

You can setup targeted discount codes for 1 or more products, and/or 1 or more collections.

So, when a subscriber receives the discount code or just clicks on the discount link, the custom discount code will automatically populate during checkout and will only work for the configured products/collections.

Note: This feature is exclusive to Shopify stores.
