CustomDUO Shop

UK Delivery


UK deliveries are shipped using a Royal Mail Signed Delivery service (except low value orders, <£10). Postage is calculated at a flat rate, based on the total amount of the purchase, as follows.










International Delivery


International orders welcome. We deliver to most (but not all) international destinations, using Royal Mail. We reserve the right to cancel and refund any order to any destination if we have any concern over it arriving safely. Feel free to contact us if you live off the beaten track or somewhere with a shocking postal service!! We also reserve the right to cancel low value international orders if delivery is not cost effective.

International deliveries are shipped at no additional postal charge (i.e. at the same postage rate as UK deliveries) using Royal Mail International Standard service. We obtain proof of postage for all orders. If you would like the security of delivery by the Royal Mail International Tracked service, then there is an additional shipping charge of +£5 to be added to your order.
