How do I change the default Apple payment method?

Here's how to change the payment method order for your Apple account after Apple account balance (which will be charged first in all cases unless the item you are buying cannot be charged to account balance). For the first four steps, refer to the first image in this Support article Add a payment method to your Apple Account - Apple Support where it says to tap Edit to reorder or remove a payment method.

1. Tap on the Settings app.

2. Tap on the Apple ID section at the top of the page (your name).

3. Tap Payment & Shipping (on old versions this is iTunes & App Store).

4. Tap Edit.

5. Tap and hold on your preferred Card and drag it up or down the list.

6. Tap Done.
