How to pay order (eBay)
After committing to buy an item using "Buy It Now" option, just proceed to checkout. If you just added the item to your cart, click on "Pay Now" button next to the item. If the "Pay Now" button is not available, select "Proceed to checkout".
When you check out and pay, make sure to verify or change your delivery address. If your PayPal account is linked with your eBay account, you'll just confirm and pay. If it's not linked or if you don't have a PayPal account, you can select another payment method, such as a credit or debit card. You'll then confirm your order details and pay through PayPal guest checkout.
If you're having trouble paying for an item, check your PayPal information, debit or credit card details, and the email address registered to your eBay account. If any of these are incorrect, you may have to update them before you can pay.
