As of yesterday, Mein Kampf is the top seller in Amazon's Propaganda & Political psychology section, and 12th in the Politics & Current Events section of the iTunes e-book store, according to The Huffington Post.Print sales, however, have remained stagnant; it hasn't been on The New York Times's nonfiction bestseller list since the year of its release.Why the sudden surge in interest? One explanation is that, while many versions of Mein Kampf exist in various formats, the 99 cent Kindle version was released in January of last year, The Huffington Post reports.
