Is buying this bundle "predictably irrational"? If you read the first book in the series you will find a story about bundling and distractor options when purchasing a magazine. The point is the company persuades the consumer to purchase a bundled option by pitting it next to a less attractive but similar option. Given that this is a main theme of one of the opening chapters, it seems ironic that there would be a bundled option. I am trying to picture the conversation Dan Ariely had with the publisher/marketing consultant over this. However, I still feel like I've gotten a bargain so let's do the math to see if my "predictable irrationality" was a poor decision. The bundled kindle version of Dan Ariely's 3 books costs $16, a little more pricey than the average book I buy. Buying the three books separately would cost $9.78, $8.99, and $9.99, respectively for a total cost of $28.76. I'll tell you the truth though, I have not yet read the latter two books (just Predictably Irrational), but I would gladly wager the $6.22 difference between the bundle and the Predictably Irrational price. Dan Ariely's bundle seems to pass its own litmus test for rationality. Oh, and it's a great read.
