How to Order

The easiest way to order is to click on the PayPal button on the page of the book(s) that you want to order. You don't have to have a PayPal account to use the PayPal system. We accept also accept orders via e-mail, US Mail, or phone. In addition to PayPal, we accept VISA, Mastercard, AMEX, and Discover using SquareUp credit card processing.

Shipment is usually via USPS Media or Priority Mail Flat Rate Envelope for orders of one or two books.

As noted on our Home page, we have found eBay to be the most reliable way to ship international orders. Please contact us; note that we already have an eBay page set up for Number? and Project Risk Quantification and Your Mother Should Know.

For orders of three or more books, we usually ship either via FedEx Ground or USPS Flat Rate Medium box.


Contact us for quantity discounts. As noted on our home page, we sometimes have slightly damaged books that were returned from bookstores, so if you are on a tight budget, contact us!


We normally do not provide free academic copies. However, most of the time we have slightly used books that we can send out for academic review. Contact us for availability. We have instructor materials for some of our books. Also, we can set up a special web page for your students and offer them an academic discount if they purchase from us (we're doing this for several colleges now).

Electronic Versions

We have lowered the Kindle and iBookstore prices to $9.99 for all of our books except Introduction to Decision Analysis and Introduction to Bayesian Inference and Decision. These two books were printed via offset and are not available for eBook readers.
