Now that The Discipline of Organizing is available in print form, MIT Press has pushed the content-equivalent ebook versions into the usual channels. It didn't surprise me that Amazon was the first to offer an ebook version, but I was surprised by the pricing. The list price of the print book from MIT Press is $40, and Amazon is offering it for $30.63, a 23% discount. The list price for the digital version is $39.99 (I guess the marginal cost of printing, warehousing, and distribution come to 1 cent), and the Kindle version is offered for $27.95, a 30% discount. I expected the digital version to be much cheaper.
