Yahoo! Wallet is a service that securely stores your credit card, billing, and shipping information so you don't ever have to type it in again. It makes shopping on Yahoo! safer, easier, and faster.

Express Checkout also allows you to easily save and retrieve your payment information for future purchases made from your computer. The next time you buy products or services from Yahoo! on your computer, your payment information is pre-filled and ready to go. For security reasons, you're required to log in using your Yahoo! ID and password each time you wish to access this payment information. In addition, this information is only available from computers on which you've activated the Express Checkout feature.

With either of these services, your payment information is stored securely and you can edit it at any time by simply going to the Yahoo! Wallet web site.
