To remove your Yahoo! Wallet, please follow these steps:

1. Go to the Yahoo! Wallet home page and log in with your Yahoo! ID and password.
2. Enter your Yahoo! Security Key.
3. After you've entered your Yahoo! Security Key, you'll see a screen that displays your billing and shipping information. Click "Delete Wallet" at the top-right of the screen, and your Yahoo! Wallet will be removed.

You'll still have a Yahoo! Security Key, which you can use for other Yahoo! services. If you want to use Yahoo! Wallet again, grab your credit card, because you'll need to re-enter that info. Your home or work addresses will still be stored at Yahoo!—you can edit or remove them by going to Yahoo! Account Information.
