Bundled products allow you to specify a group of products for purchase as part of a single offering. It also allows you to set a price that may be different if the products were purchased individually. The top level product will allow you to specify the price for the bundle. Each of the products listed here will be included with this top-level product. The top level product will also inherit the Entitlements from the "Bundled" products.
As with all products you can override the price at the billing plan or subscription.
