It has little to do with the price being set by a computer or a person. He sees the price for everyone else is one third cheaper. He doesn't say it, but without making the connection to the price fixing anti-trust action, a reasonable conclusion would be that since the book is one in a series, and Amazon knows he bought the previous book, it has jacked the price for him since he's already "hooked." That to most people would be a questionable pricing strategy. The anti trust action makes more sense, but he probably didn't make that connection.
