Here’s an intriguing app pricing strategy, from London financial newspaper City A.M. In the capital, you can pick up the print edition for free. Yet the app costs a whopping £22.99 on the App Store as a one-off paid download. Once paid, it provides daily digital editions of the newspaper, as well as breaking news throughout the day. Facebook and Twitter sharing is also included. But that price is startling, given that the print product is free and ad-supported.
