Apple Inc. (NASDAQ:AAPL) seems to be testing promo codes for in-app purchases inside of Apple applications. This way you can specifically gift items like levels for a game or virtual food for your virtual pet.
Screenshots of redemption codes for an EA game has been leaked to Jeff Scott as you will notice above. The “Handful of Gold” in-app purchase that you will notice in the screenshot is generally valued at $2 otherwise.
You will be able to use the code whether or not the user has the original app installed. If they already have the app installed, it will unlock the in-app purchase. If they do not have the app installed, it will be automatically installed.
