Yes, you can.
You can change your credit or debit card details in PayPal to make payments to pre-approved billing easy. This section will help you update your payment method in PayPal (also known as payment source) so that their order can be charged. This will help you if you are notified that your payment is declined or if you need to update an expired/incorrect credit card.
Alternatively, you can also choose to add money to your PayPal balance. This is the easiest method to cover the cost of the purchase.
After making changes, please notify your seller so that the order can be charged.
