What IAP type Should be Used for Magazine App Like Zinio?

Apps that use IAP to purchase items must assign the correct Purchasability type We found that the Purchasability Type for one or more of your In App Purchase products was inappropriately set, which is not in compliance with the App Store Review Guidelines.

Your In App Purchases are set to Consumable.

However, based on product functionality, it would be more appropriate to use the Non-Consumable In App Purchase type. Non-consumable products are only purchased once by users and are always available on all devices that are associated with that user's iTunes account.

We are using consumable type of in-app products since we have a lot and frequently released magazines with different prices therefore we cannot define the purchases to be non-consumable.

We have set pricing Tiers from $0.99 until $54.99 so that each magazine will be classified appropriately and assigned to a certain Tier.

our system has a lot of magazines where each one has many issue releases. Magazines issues are sold within an offer.

We have "single issue offers" (offers containing only one magazine issue) and "multiple issues offers" (offers containing multiple isses, eg: get 3 digital issues of magazine x for $19.99).

We are using the Tiers from 1 to 55 to assign prices for our offers. Note here that the in-app purchases are consumable but our system won't let the user buy an already purchased item another time.

The application will contact our server each time when the user attemps to buy an offer.

If the offer is already bought, the application won't proceed with the in-app purchase and the user will be shown that he has already bought that offer.
