Another month, another monthly bestselling list dominated by reduced price Kindle books. Our readers are apparently a value-sensitive bunch and picked up a slew of copies of The Honest Truth About Dishonesty: How We Lie to Everyone–Especially Ourselves by Dan Ariely. On the investment book front Ray Dalio’s new book Principles: Life and Work debuted to great sales.

For more book ideas you can check out our latest post compiling our many book links as well as last month’s best-sellers list. We present sales two ways: the first is by unit sales and the second is by revenue which can be notably different. Here are the books (combined print, Kindle* and Audible.com) that Abnormal Returns readers purchased at Amazon during September 2017:
