Theater owners don’t want to keep adjusting prices for tickets and concessions based on the movie or time of day, but they also don’t like seeing 88% of their seats left unfilled. That may create an opening for Dealflicks, a Priceline-like service that enables exhibitors to offer discounts tailored to their needs. CEO Sean Wycliffe tells CNBC today that Dealflicks just introduced an iPhone app, and is signing up theaters at the rate of about 2 a day.
