Slightly revised version for you:

Use your credit card to buy an iTunes gift card at any retailer, and then Redeem it to your iTunes account.

The best way for convenience. On your IOS Device! If you already have your credit card set up to your account. Go to the App store. On Features page scroll to the bottom and hit send gift. Send a gift card to yourself(your email address) in the amount that you want. Your credit card will be charged immediately. Once done open the email and it will direct you back to the app store to redeem your gift card. Your Welcome!

You can either use a credit or debit card to connect to your account or you can purchase iTunes cards. If you are using the iTunes cards, the instructions are on the back and it tells you how to add the funds using your computer or your mobile device (iPad, iPhone, iPod). 🙂
