Support Buy X Get Y discounts with pre-order items

The merchant would like to run Shopify’s native Buy X Get Y discounts where the “Y” item can be a pre-order product. Currently, when a product is set as a pre-order, the app injects a pre-order selling plan into the “Add to Cart” button. This ensures the product is properly recognized as a pre-order when added to the cart manually.

The challenge arises when Shopify’s discount rules automatically add a “Y” product to the cart. In these cases, the pre-order selling plan is not applied because the product bypasses the app’s pre-order button. As a result, the system does not recognize it as a pre-order and the discount fails to work as intended.

Adding support for BXGY discounts with pre-order items would allow merchants to seamlessly combine promotional campaigns with pre-order sales, creating a smoother experience for both merchants and their customers. If this feature would help you too, please give it an upvote!
