The App Store Volume Purchase Program allows educational institutions to purchase iOS apps in volume and distribute the apps to their users.
Program Benefits
With the App Store Volume Purchase Program, your educational institution can buy Volume Vouchers using a purchase order, credit card, or PCard, then use the vouchers to purchase iOS apps in volume and distribute them to multiple devices.* If your institution is tax exempt, you will not be charged sales tax when you purchase apps. The program also allows app developers to offer special pricing for purchases of 20 apps or more.
