I got a copy of "Fish: A Memoir of a Boy in a Man's Prison" through Giovanni's Room in Philadelphia. The cost was $14.95 plus $5.00 shipping. I usually wait till I am ordering more than one book because the shipping cost remains the same. Delivery is usually in a day or two. I like the idea of supporting independent gay book stores and my experience w/ Giovanni's Room has always been very positive. They are pleasant and knowledgeable.
