Amazon Kindle, Expired Credit Card and Gift Card Balance issue

Ran into a weird problem with the Amazon Kindle in our household. They don't let you purchase a new book when you have an expired credit card in your one-click setup, even if you have a gift card balance on the account. We couldn't figure it out on the Kindle, so I had to login to Amazon, delete the expired credit card, and then the purchase went through with no problem via the gift card. It's funny because with so many of these devices today, when you actually have to break out the computer and go to a website, it feels jarring and old-fashioned.
