What are Extra Payments?
Extra Payments are typically used if a customer needs to add something to their original order (which will then make their order cost more)
If you haven't been asked to make an Extra Payment, or do not know what it is referring to, please do not use this tool.
You will only be able to make an Extra Payment by Paypal or card, unfortunately Klarna is not available for this function.
You can always ask Customer Services for any help with extra payments if you feel unsure about this process.
