My credit card was declined, can you run the charge again?

Apple maintains the App Store and processes all charges. For your security and privacy, only Apple knows your purchase, payment, and credit card information. If an App Store credit card charge is declined Apple will usually resubmit the charge again.

In certain circumstances where the charge is suspected of being fraudulent, the credit card company may continue declining the charge and you may need to change the credit card on file with the App Store.
