Come for the price, stay for the quality
A project like this doesn't happen without some expenses. And I would like to demonstrate to other authors that publishing textbooks with open licenses can be a viable alternative to using a traditional publisher. Thanks for your support of this experiment in providing quality textbooks at reasonable prices. There are several easy ways to donate.
(2) The donation version at Lulu.com is a $6.55 PDF version of the book ($5 to the project).
(3) Dwolla is a payment service like Paypal, with low transaction costs.
(4) A check (in US funds drawn on a US bank, please), is another way to go. US or Canadian cash would be a final resort. My postal address is:

Purchase Physical Books
Lulu.com is a print-on-demand service where you can get a copy of the book for $29.70 (as of 2011/11/30).
The most recent edition is known as the Waldron Edition, and is a subset of Version 2.00 content. Because of binding limits, it does not contain the additional topics, and the Archetypes are split out as a separate workbook ($8.90). $5 of the price of the book will be used to support further work like this.
Head out to the Lulu Storefront
I have found Lulu's prices competitive with those charged by copy shops for bulk purchases (30 copies or more) with an educational discount, and half the cost of a single copy at a copy shop or my university's bookstore. At a typical cost of 5 cents a page for laser printing, doing it yourself would cost $39. And none of these comparisons include a binding and a cover.
Lulu.com will handle all of the details related to your payment, and will ship your copy to you directly. In the United States, USPS Media Mail is relatively inexpensive and reasonably quick (1-2 weeks). Due to the nature of print-on-demand, it is not possible to accomodate refunds - be sure to preview a downloadable copy before purchasing.
