Online payments are processed securely using Stripe. We accept all major credit cards. We also accept credit card payments over the phone. Call us at (845) 726-4444.

Purchase Orders

We accept institutional purchase orders, which must be signed by a person authorized to approve the expenditure and faxed or mailed to us.


We usually process orders within 24 hours of their receipt during the work week. Delivery times are typically within six working days of receipt of the order for people living on the West Coast of the U.S.; the closer you are to our shipping point in downstate New York, the less time it usually takes for an order to reach you. In most cases, eBooks are delivered automatically and immediately upon receipt of payment.

We ship via the U.S. Postal Service or UPS, depending upon the size and configuration of the order. We try to honor any preference you express. We will ship via expedited service if you request it and indicate in the comment field your willingness to pay the additional charges for it.

If you provide an email address when you order, we make the extra effort to ensure that you can track your packages.

International Orders

For orders from outside the United States that are placed online, our system will not charge shipping. We will notify you of the shipping cost, which you can pay via Stripe.

MCT Packages or Multiple Books: You can always email us to discuss the shipping cost, but as a general rule, they are sent in U.S. Post Office International Priority Flat Rate boxes.
