In an experiment, a group of clients paid their subscription to a theater series full price, while two other groups received discounts.
Customers who had initially paid more for a season attended more plays during the next 6 months, because they experienced a higher sunk cost when they purchased the season tickets.
Customers are more motivated to continue using a product or service if they have already invested a significant amount of money in it.
