Limit product shown for upsell
Upsell products to customers pre-fulfillment.
Order Editing offers customers the ability to browse all products that have inventory available, pay for additional products and add them to their existing order.
If you want to limit customers to a specific collection or set of tagged products, you can add a search query in the customization block, located in the apps customization settings. This will ensure that customers are only able to search and add products that meet your queries criteria.
