All material is offered subject to prior sale, and remains our property until paid for in full. All material is returnable by the purchaser within one month of receipt, for any coherent reason, and with notice provided beforehand. Manuscripts may attract VAT in the UK, and both these and printed books with significant manuscript content require UK Export Licenses for export abroad. Insured carriage (by courier for expensive items, unless otherwise arranged) will be billed at cost. Any import duties and/or processing fees are the responsibility of the buyer. Customers unknown to us will be invoiced pro forma.
