My credit card was charged more than the app price

Apple bundles any credit card charges made during a 24-hour period for apps and other iTunes purchases (such as music, TV shows, and movies). If you see a credit card charge from Apple for more than the price of the app or app bundle, it’s because the charge includes other items. 

Please refer to the following Apple Support article for instructions for reviewing your iTunes purchase history:
