To update your payment information, you first need to log in to your account. Once you've logged in, you can access your Account Settings via the My Account drop-down menu located in the top right-hand corner. (If you're using our app, you can navigate to your Account Settings by selecting the person icon located at the bottom of the screen.)
You can update your payment information in the Payments section.
You should see your current credit card listed here. Click Edit to adjust your current card's information or Replace on the bottom left-hand corner of the listing to remove the current card and replace it with a new one.
If you want to add a second card, go right ahead! You can add a new card by clicking the Add a Card button on the right-hand side of the page. However, if your card has expired, adding a new card won't remove the old one—in those cases, you should replace your old card instead of adding a new one.
