How do we purchase Read2Go in volume?
Your school must enrolled in the App Store Volume purchase program (https://volume.itunes.apple.com/store).
Once enrolled your school can buy Volume Vouchers using a purchase order, credit card, or PCard. Program facilitators purchase Read2Go with the vouchers and get app codes. End users use the app codes to install Read2Go onto the Apple device.
