Courier companies allow you to spend between $3.50 to $20 to have a parcel delivered across town. Same parcel, same town, same distance. The price is determined by your choice as to the urgency of delivery.
Car hire companies understand people will pay more for space or power, while others just want to get from A to B. So, they offer options, and the customer is left to decide. Why let the hire company fill up the tank at 3 times the price, who would pay $150 when the same amount of fuel is only $50 at the petrol station outside the airport? It is ridiculous to think anyone would do this…unless they were running late for their flight! (A word of caution here, I do not recommend profiteering and do not  support this care hire practice I mention it to prove a point about decision making processes.)Â
Customer choices abound in hotels. Choose your room and bed size, eat in the restaurant or order room service, buy drink in the lobby bar or from the mini bar.
Chelsea is one of the most popular football clubs in the world. They play in front of sell out crowds every week of the season and demand for season tickets exceeds the capacity of the stadium. Even so  each season seats are held in reserve for visitors to London, by reserving space, they can offer tourists entry to games at a premium.
