Bundled Products And Options
Bundled products and options can be used to offer discounts to customers who purchase multiple products at a single time. Discounts can be specified on one or more options in a bundle. In the cart, bundled options act the same as regular options, and are displayed as a single line item with each option in the bundle listed along with the bundle discount. For more information on creating bundled products and options, see Adding a Bundled Product and Product Option.
In addition to allowing you to bundle several products with a discount, the same product and/or option can also be placed in a bundle multiple times. This allows setting up discounts such as "Buy 1 Get 1 Free" or "Buy 1 Get the 2nd at 50% Off".
