Hi,
We are developing an Audio tour application for a tour comppany in which the app itself is free and users will in-app purchase audio tours (example: New York Walking Audio tour, Las Vegas walking audio tour). Our issue is that we would like to offer the audio-tours for FREE if the user is an existing customer of the tour company.
We looked into doing promotion codes for in-app purchases but it seems this mechanism is not available by Apple nor are you allowed to roll out your own.
I'm wondering if we can provide a members-only login within the application. If a user logins in, the in-app purchases become FREE - they don't go to the store but actually just do a straight download. Apple doesn't provide guidance on this matter for us and we are wondering if anyone has experience around this or something similar.
Scott
