There are two ways to update Amazon Pay information. Just updating your default card on Amazon is not enough.

Go to Amazon.com and when you access your card, click on “Use this card across all of Amazon”

Alternatively, go to https://www.madison-reed.com/account/profile/info then scroll down to Payment Method and click on “Edit this payment method” and you’ll get redirected to a page that will have you login via Amazon and give you the chance to add/change your Payment Method.
