&gt;- I feel that in many cases, ebook prices are just ripping me off.<p>I think this is really informative for people who price things, not just for the ebook subject.  e-book prices are usually lower than print-book prices.  But people feel ripped off, because they know it took the publisher zero marginal effort to make their copy.<p>I mean, I&#x27;ve been on the other side of this, too... I was really surprised when my royalty check came, because if someone buys the e-book alone, I get a massively higher royalty than if someone buys the print book.  - so if you are the sort who thinks the author should get paid more and the publisher should get paid less, then e-books are for you.<p>but... really, the interesting thing is just how intuitive the &#x27;labor theory of value&#x27; is-  we expect the price we pay for a thing to have something to do with the effort and capital that went into making it, and we feel ripped off when it doesn&#x27;t.
