If you are receiving a payment error regarding your Postcode, this is due to the postcode you have entered not exactly matching the postcode your bank has on record. This could be either an incorrect or out of date postcode for the card you're using, or simply a formatting issue (capital letters and spacing). Please note that we do not have any control over payment gateways and you will need to contact your bank directly to resolve any issues. If you're still having problems with your order, please feel free to contact us and we can try and troubleshoot as best we can in order to get your coffee delivered to you.
