Have you noticed how things at the airport inevitably cost more? Because you are captive in their realm, you must pay more for your coffee or your burger. It's true of movie theaters and state fairs too - once they have you, they want to take as much money from you as possible.
Do we do this in church? I know most churches don't have a food court, but often church related items cost more than they should. Books, music, and software for Christians can be quite a bit more expensive than is really necessary.
Do you think it's fair to charge more for Christian media?
