Since the Business Model Toolbox iPad App is downloaded through the iTunes store, Apple tightly manages all commercial actions, including purchasing, installing and account transferring. Any questions should be addressed directly to Apple's support.
However, We do have control of the development of our similar Strategyzer App and would be happy to grant you a USD $30 discount on a one-year project subscription. Please visit strategyzer.com/app to learn more about all the features available within the Strategyzer App.
Contact firstname.lastname@example.org and provide proof of purchase of the Business Model Toolbox iPad App to receive your discount. You can contact Apple's support by following http://www.apple.com/support/itunes/contact/.
