Review before paying

Check your cart, quantities, delivery address and order total. Select one of the payment options shown at checkout and follow the instructions from that payment provider.

If payment does not complete

Read the error message and check your billing details. Before trying again, look for an order confirmation and check the order status. If your bank shows a charge but the website does not confirm payment, contact support with the order number and transaction reference.

Keep sensitive data private

Never email a full card number, card security code, password or one-time authentication code. A transaction reference and a screenshot with sensitive details hidden are sufficient for an initial support request. For payment options not displayed at checkout, ask support rather than assuming availability.
