You can delete the Credit Cards in your Account. You just need to choose the card you want to delete on your billing page and click on “Delete Card”.
If a card is tied to the membership, it cannot be deleted until the membership expires. So, “Delete Card” option is not available for the card that is linked to Membership.
Once the membership expires, the card linked to the membership unlinks automatically.
If you’d like to change the payment method for your membership from credit card to Store Credits or PayPal, you can do it in the Yellow Ticket section of your account. To find a step by step guide on how to do that, please visit this article.
