The business concept of bundling products and services is far more than just adding a service to a product. It deals with a new market concept, where the bundle attracts customers who wouldn't buy the product without bundle. A well known example is market development the mobile phone.
phone as such was considered (and still is) as too expensive. The problem
was (and still is) that the costs are higher than the perceived value. So
one may conclude that there is no market for mobile phones.
However the service of a telecom company (connecting people at any moment they want) has a high perceived value (say. 0,40 € per minute) in combination with low costs (say. 0,10 € per minute).
The marketing trick in such a case is to combine the product and the service in one bundle.
See Fig. 3.3 .
Note: Even now, in a mature market of mobile phone services, it appears hardly impossible to stop with the marketing concept of the bundle (KPN tried): only very few people are aware of the financial consequences of the bundle and rather buy the product and the service separately (which is cheaper). The negative result for the environment is that people throw away their old mobile phone (before they otherwise would have done it) each time they enter a new contract (say every two years).
