Please add 8.375% sales tax for any order sent to a Nevada address (unless you have provided an official resale or tax exemption certificate). All items are guaranteed as described. We take pride in our book descriptions. Every item is meticulously examined so that condition and edition are listed as accurately as possible. We strive to provide pertinent bibliographical details. In addition, our listings frequently include content summaries, details on provenance, and/or biographical notes on the author. Our descriptions are protected by copyright, and unauthorized use is strictly prohibited. Violators will be prosecuted. We always take the time necessary to carefully package your order so that it arrives safely and securely. Shipping cost estimates are based on an average size book and are intended to cover only our actual expenses. If your order includes multiple volumes, oversize, heavy, or valuable items, we may contact you to request authorization for additional postage. RETURNS: If not as described, your order is returnable within 10 days of receipt. Prior notice is requested and appreciated. Returns must be securely packaged and arrive here safely. A full refund will be issued if the return is attributable to a mistake on our part; otherwise shipping costs are not refundable.
