You can update your existing card information or add new cards by going to the "Wallet" tab at the top of the screen.
From here you can select the trashcan icon to remove a card from future billing, or the pencil icon to edit the card's information.
You can also add additional cards by selecting the "Add New Entry" option.
Once you've added in the new card information, click continue. This adds the card to the account where it can be used for billing purposes. If you have any questions, give our support team a call at 866-774-2947, or by email at email@example.com!
