Buyers will be less price sensitive the higher the costs (monetary and nonmonetary) of switching vendors. Airlines that have a fleet of Boeing airplanes may be reluctant to switch to Airbus because of the enormous investment they have in their pilots, flight crews, parts inventory, and the mechanics of operating a certain plane. Many people are unwilling to give up certain software products due to the learning and familiarity they have with their existing product. Personal relationships are most susceptible to this type of perceived cost, due to the emotional investment the customer has made in the relationship.
Childcare providers, doctors, lawyers, and accountants all can benefit from this effect, especially if they provide Total Quality Service.
