Trade orders

Thank you for your interest in our titles

All of our published titles are available unless they are stated as out of print, which currently none of them are. There is no need to contact us first to check if titles are available.

Retail: All titles can be purchased directly from our online store. Most retailers of non-specialist, general titles do not keep our specialist titles in stock. Hence, even though other sources may advertize our books for sale, even stating they have them in stock, most of them do not have physical copies of our specialist titles immediately available (they order them from us when they get orders). Hence, the quickest way to get our books is to order directly from us. Follow our blog and Facebook pages for periodic discounts.

Trade: New customers please email us with your specific requirements (books@siriscientificpress.co.uk). Our titles are also available via Bertrams, Gardners etc. even if they are not all listed as 'in stock' in their catalogs. While they may not stock all our specialist titles they do still order them from us when they get a trade order. Trade orders will be sent with an invoice (trade discount is 33.3%). Payment can be made by BACS or by cheque in GBP made payable to D. Penney. If required we can also generate proforma invoices via paypal.

MOST ONLINE BOOK PURCHASES SHIPPED BY THE NEXT WORKING DAY! PARCELS OVER 2KG ARE SENT BY COURIER ONCE OR TWICE PER WEEK.

All Siri Scientific Press books are brand new and unused when shipped. They are usually sent in padded jiffy envelopes or cardboard book envelopes (apart from large orders). We do not accept any responsibility for goods damaged or lost in transit. If you are interested in other forms of packaging or recorded delivery etc. please email us for prices. We always keep proof of postage. If outside the EU you may be liable to customs and excise charges in your home country. Siri Scientific Press can accept no liability for these or for delays as a result of items being held by customs officials at the port of entry.
