WINDOWS OF PERCEPTION [SIGNED Inscription by AUTHOR]

Books are shipped within 2 business days of the sale and all of our items need to be paid in full before shipping. For dealer-direct payments, books may be held for no more than seven (7) calendar days while awaiting payment - exceptions can apply upon prior communications and approval with NES Books.

We consider Saturday, Sunday, and U.S. Holidays to be non-business days. Books may be returned within 15 days of receipt for any reason. Books must be returned in the condition in which they were received. Return shipping costs are paid by buyer, however; if we make an error we will pay return shipping. We make every effort to describe our books (including negative points) as completely as possible.

We ship USPS media mail in the United States. Our default shipping service for Priority shipping and International shipping is USPS. Priority and International rates are more. We do use UPS or Fed-ex on some occasions or upon request at additional charge.

International shipping times may take longer than expected due to customs, weather or the destination country mail service. See our shipping matrix for any questions about rates and shipping time estimates.

International customers are responsible for paying any taxes or import duties that are owed as we do not pay duties for items, nor are they added to your shipping costs. Tracking or insurance on International Priority Mail shipments is often not available with USPS. If tracking and insurance is required, please select Express Mail International or inquire about Fed-Ex or UPS costs.

When multi-volume sets, exceptionally large or heavy books are ordered additional shipping charges may be assessed.

We are very sorry for any inconvience, but due to fraud concerns we do not accept checks, cash, money orders or E-checks. Due to the popularity of online book sales and the limited supply of books there may be a time when a title has already been sold. We function on a first come basis based on time of the first order.
