Currently, product bundles can only be set up with a promotion, but this bundle discount only works for a single bundle. Ordering a bundle of A+B products works, but if you try to order two or more A+B bundles it does not. Customers can also take advantage of the bundle system. If you add a bundle of A+B, you can add an unlimited number of B at the bundle discount rate. Need an actual product bundle feature that works without the need of creating a promotion and applies to multiple quantities.
