You must purchase the app that this item is for before you can purchase the itemBy
If you get this message “You must purchase the app that this item is for before you can purchase the item” while trying to buy Smurfberries it means you are using the wrong iTunes account. This happens if you have more than one account. You can only buy Smurfberries with the same account that was used to download the App. So if this message comes up, just go to the App Store and sign out of your current account. Then go back to the Smurfsvillage App and sign into the correct account when asked to sign in before completing the purchase. This should help.
