I now sell a limited number of paperback books directly from me, for 25% off the Amazon list price. Occasionally I run a 50% off flash sale or offer limited-time items that are largely discontinued. These limited-time items are also 50% off. Signed copies are not available except by prior arrangement. If you're interested in a signed copy or personal note, use the form on the contact page to get in touch. Allow minimum 3 weeks for shipping.
