Yes! Next time you are placing an order at the Checkout click on the 'Change credit card' link below your saved details. Then you can enter the new card and the details will be saved when you complete your order. To delete a saved card click on the My Wallet option on your profile, select the card that you wish to delete and click on Delete Card. You can still have an account with no saved payment details. And if you feel like adding new ones later there is a tick box at the bottom of the checkout to save them. Please note that for security reasons we cannot delete your card details nor are we able to view them.
