In a competitive market, why is movie theater popcorn expensive?
Theaters make pennies off the tickets if any money at all. Their profits come from the concession stand. If a theater priced their popcorn 50 cents less than a nearby competing theater the few if any customers that notice and seek those small savings would be far less than the losses due to charging less. They compete to get you there: providing better sound systems, seating, screens -- even taking a loss on tickets with special deals (like Tuesday bargains). Once inside profit is made by customers willing to pay the concession price premium, and sour patch kids for 15 cents more isn't going to be a deal breaker.
