Good Afternoon Gareth.
Firstly please accept our apologies, unfortunately we have not seen any correspondence from you giving us the option to respond. When multiple purchases are made via our website, they system automatically multiplies the postage and can't workout multiple items packed together ( we have a message on the payment screen to contact us if you think the postage has become excessive). Obviously in this case you have continued with the order and unfortunately we have not seen anything to enable us to process the order manually and reduce the postage costs. The postage on these items (when packaged together) should be £10. As such we are happy to refund you the difference of £20. If you could please contact us via email at classicpanelcompany@yahoo.com and supply your bank details we will be happy to process your refund. Once again, we apologise for this situation. Should you wish to order multiple items from us again please give us a call (number on website) and we will process your order manually in order to secure the best price for shipping.
EDIT: Thank you for sending us your account details, your refund was arranged and paid immediately.
