Problem:

How to redeem Promo Codes From Within the App Store



Solution:


Yay! You’ve finally won a contest here on iPhone.AppStorm. You’re on the go when you find out, but you don’t want to wait until you get back to your desk to fire up iTunes.

Here’s what you do: open the App Store app, go to the Featured tab, scroll to the bottom, and tap “Redeem.” Now, tap in that promo code. This also works with iTunes gift cards.
