Interesting how used ERE books are offered for more than a new book (ranging from $12-$37).

Many of these offers are quite likely from resellers who buy the book from the publisher at a reduced rate. They do not actually have the book in inventory. If someone is dumb enough to order at the higher price, the reseller will order the book from the publish and immediately turn around and ship it to whoever bought it "used".
The 3 weeks in spring 2011 when the book was not in print all these resellers mysteriously vanished. During this period the real used price was trading upwards of $20 compared to the initial amazon price of ~$15. A few people made money flipping the ERE book.

I can tell from my sales channels that those algos are not working at all. Nobody buys from them.
Sometimes two will compete on insanity. E.g.
Algo#1: Always set the price 2 cents higher than the next one.
Algo#2: Always set the price 1 cent lower than the highest.
Together #1 and #2 will drive their pricing into the stratosphere.
This is part of the reason why you sometimes see books costing $999.99 ... or in the opposite direction why books suddenly go on sales (<- that's a good way to get a cheap used book on amazon).

There are whole species of other bots that infest the Amazon Marketplace, pretending to have used copies of books, fighting epic price wars no one ever sees. So with “Turing Test” we have a delightful futuristic absurdity: a computer program, pretending to be human, hawking a book about computers pretending to be human, while other computer programs pretend to have used copies of it. A book that was never actually written, much less printed and read.
