everything is guaranteed to fulfill our expectations of and anticipation of value. When it fails, we simply don't buy that brand again, or buy that author's work. But to say that a book isn't worth, say, $8.99 or even $29.99...I ask myself what it would have taken for me to otherwise create/gain the insight/value I obtained from simply reading a book or listening to the song. I pay exclusively for the perceived value of the content. the essence of the question of value is... well, read Dan Ariely's books! People are not rational when it comes to judging value. Things are relative and emotional and complex. It is completely unrealistic to try to prescribe some logical way of assigning value. Whatever weird things people think, such as how many times they will read a book, it's all part of how people think. And it's not gonna change. People will never be the mythical rational beings assumed by traditional economics. its only an opinion, in my situation 8 is a lot of money for a book I would only read once, books are something that myself I generally buy, I am currently reading something I was given by a friend, I would never have thought to buy it, even at such a low cost but i am enjoying it, films, tv programmes are often too pricey for me, I regularly buy Ross Noble's DVDs as I want to support him, but in truth I feel everything is too expensive and that
