As reader Paschal Stewart alerts me, they're actually offering Mad Art over at the Quality Paperback Club. In fact, they say it came out last November and if you're paying the fee to get a membership there, you can buy it for two dollars! How is it they have copies? And how can they sell it so cheap? Simple. If you study their listing above and look carefully, you'll see that they're selling an edition that has ZERO PAGES!
That's right: No pages! It's easy to get a book in stock if you don't wait until the insides are printed. And you can sell those copies real cheap — though I'd think an Evanier book without pages should go for more, not less.
