Bundling is a term that refers to several products (goods or services) marketed and sold together; yet, each of the products should be able to sell to a market segment of their own. Bundling usually involves price bundling. The products in a bundle are often chosen such that the customer's needs are satisfied better or to provide better value to the customer. Bundling in the form of introducing a new product together with an established one is found to particularly facilitate the adoption of radically new products. It can also be used when disposing of lasting stock of a product that is to be taken off the market. Such bundling must be done with care so that the customer can make an informed choice. Whenever bundling, marketers must avoid creating bundles that may be seen as obstructing competition.
