Use computers to calculate book prices

This is not a numismatic post; it is about the pricing of uncommon books.

The blog “it is NOT junk&rdquo noticed a book on fruit fly DNA selling for $1,730,045.91. Instead of assuming a typo the blogger followed the book and watched as the price rose to an astonishing $23,698,655.93 then crashed to $106.23.

It's suspected that no human entered these prices. Instead, two competing stores probably used computer algorithms to price the books.
