With the latest version of the app, bundled-type products no longer work with Shopify discounts. Shopify’s bundles feature does not support adding a bundle into another bundle.
Here’s what happens:
When a bundled product is added to the cart, our app's bundle breaks apart, and the individual items get separated. At that point, Shopify applies its discount to each separate item.
However, if none of the items in your bundle is itself a bundle, the discount won’t be applied. This is because the bundle is treated as a single product with one variant.
If you want to offer discounts on bundled products, we recommend using our app's automatic discount feature. This ensures the bundle remains intact, and the discount is applied correctly.
