How do I use the same credit card? I do not want to add a NEW one!

Hi pzarick1

welcome to the Apple (user-to-user) Community.

Re: "How do I use the same credit card?"

Check what payment methods Apple can accept in your country or region:

Payment methods that you can use with your Apple ID – Apple Support 

and

You might want to check that your card's expiry date is still ok

or

What to do:

If a message says 'billing problem with previous purchase' or 'verification required' – Apple Support

re: "Why will it not accept my card?"

You might want to check through this article to see if anything there helps:

If your payment method is declined in the App Store or iTunes Store - Apple Support

Eg: says: "If you want to know why a debit card, credit card, or other payment method was declined, speak with your financial institution".

Maybe international payments need to be authorised.

or

If you have disputed a charge, you may have to allow payments to Apple again.

All the best :-)
