Packages can be made up of products, packages, pricing plans, and discounts. Once you create a package, you can add new products to that package:
In the product list, make sure the desired package is selected and right-click.
Select New from the menu and select Discount, Product, Package, or Pricing Plan.
Note
Packages are the only product catalog items that may contain children, other than folders. Packages may contain products, discounts, pricing plans, and sub-packages.
The appropriate window is displayed.
Click Save when you are finished entering the information. The child you created automatically appears under the package.
