Along with its refresh of the Featured section in the iTunes App Store, Apple has added a section dedicated to educating people about in-app purchases and what they are exactly. This was most likely added to address the recent fiascos with users accidentally purchasing in-app content on their iOS device.
The user guide, called “Learn more about in-app purchases,” explains what in-app purchases are exactly, and how they work. Plus, it teaches users how to prevent their kids from gaining access to in-app purchases where they might spend a crazy amount of money on virtual goods otherwise.
