Valve may not like it, but the Windows 8 Store is coming, and more details have emerged about pricing policies from Microsoft. The most notable: the lowest-priced paid apps will start at $1.49 instead of the 99 cents that consumers may be used to from shopping for phone or tablet apps in iOS and Android stores.
Prices can rise in 50-cent increments all the way up to $999.99. Developers can choose to release free apps, and support them with in-app purchases. Unlike other app stores, the Windows 8 will allow seven-day trial periods for users to test paid apps before purchasing them. According to an MSDN blog post, apps using trial periods that are sold in the Windows Phone store have earned as much as five times as much as apps that don't.
