Billing address – Have you entered the billing address that your payment card is registered to? Your billing and shipping address can be different. For example, if you have a UK payment card registered to a UK address, however, you live in France, you would use your UK address as the billing address.
Billing telephone number – Ensure that the phone number you have entered is that which is linked to your payment card. This might be needed to receive a OTP (One time passcode) to verify the card payment.
Card details – check the card details have been entered correctly, including the expiry and CCV (3 digits on the signature strip)
Payment verification – Once you click the ‘Place Order’ button at the bottom of the checkout screen, you might see a screen requesting payment verification from your card provider or bank.
The verification process will ask you for either a OTP (One time passcode) which has been sent by text message which you will need to enter, or to verify through your payment card or banking app.
