Starting on September 30th, Google will list the price range of subscriptions and in-app purchases. This will give users a better idea of the true cost of an app.
It also might help those scared off by in-app purchases feel more comfortable with the idea of buying a freemium app.
Another change coming on September 30th requires developers to post a physical address that users can see. If a developer doesn't have an office, he or she will have to post a home address. If the developer changes his or her address, the new location will have to be posted.
To get around this requirement, there is a solution. If the developer makes an app free and doesn't offer in-app purchases, he won't be required to give away his location.
