Please note, before I was able to make the purchase I had to completely close and restart Angry Birds Seasons. You do this by:

If it’s running, close Angry Birds Seasons Bring up the quick launch menu by quickly double-tapping the round home button at the bottom of your iOS device. Now tap and hold on any icon in the quick launch menu until they start shaking and red close button appears Close Seasons by clicking the close button Relaunch Seasons and now try purchasing the Mighty Eagle again
