In all our bundle types, easy product bundles app have feature to offer discounts to your shoppers. If you want to reward your customers with discount or free shipping for taking the bundle offer, use the discount field in the campaign dashboard.
Easy product bundle dynamically creates discount codes for each campaign. You do not need create any discount code by yourself from shopify discount panel. Easy product bundles will create necessary discount code using shopify's state of the art api and attach it to the campaign. We highly recommend not to edit/delete these auto generated discount codes from shopify discounts management panel. Once modified or deleted, the related bundle offer will not work properly.
If you accidentally modify any of the discount code related to any bundle offer, we highly recommend deleting the easy product bundle campaign and recreating it. It only takes a few minutes to setup a bundle offer. Reversing the changes in shopify discount is also a choice but unless you are very certain about it, we do not suggest it.
For any question related to discount and bundle offer, feel free to contact our support.
