Shipping costs are based on Royal Mail 2nd Class Small Parcel pricing plus a small amount to cover packing materials. If your book is heavy or oversized, we may contact you to let you know extra shipping is required.

Orders are usually shipped within two business days and are packed with great care and to a very high standard. For higher value orders, our preference is to use a courier service, such as DHL. The cost is not excessive compared to Royal Mail but we will only engage a courier with your agreement.

Insurance can also be offered on any order, but at an additional cost.

Shipping speeds are estimates based on the carriers' delivery times and cannot be guaranteed. If your order will pass through Customs, please expect a delay. Any applicable Customs duties or brokerage fees are your responsibility.
