How about a brand new book? Pop Goes the Church is in stock and available on Amazon.com for $11.23. Of course, if you want you can order it from here for $16.95...but I'd personally go the Amazon route.
If you've already read the book and would like to add your own customer review on Amazon.com...that would be great!
UPDATE 11:00am: Interesting...the price switched back to $16.95. I'm guessing that must have something to do with how many books they have in stock.
