The American Booksellers Association asked the Justice Department’s antitrust division to investigate “predatory” pricing of books sold by Amazon.com Inc., Wal-Mart Stores Inc. and Target Corp.

“We ask that the Department of Justice investigate practices by Amazon.com, Walmart and Target that we believe constitute illegal predatory pricing that is damaging to the book industry and harmful to consumers,” nine ABA board members wrote in a letter addressed to Christine Varney, the assistant attorney general for the antitrust division.

This is just like everything else a big corporation would do when competing in the marketplace. They move in then undercut the competition with lower prices. When the competition is gone you will then see prices raised. It is unjust. Although with the online element of Amazon I would gather that their predatory pricing is capable of major damage.
