how the heck do you change credit card info on amazon

[Kenshindono]

ok maybe a dumb question but i dont see a 'default card' option. How the hell do you change your default credit card info on Amazon? Its somehow locked in one card that got canceled a while ago as the primary card. I am constantly finishing orders then remembering 'oops' and having to go back and change the billing option.

Theres gotta be a way to do it. Id also like to know how to DELETE cards. Theres like 2 old expired ones still on the list

When you go to your account, you have to pick the "Manage Payment Options", and it'll give you the option to edit what you need.
