If you live in a yard sale kind of neighborhood - in good weather, most neighborhoods are crawling with them on weekends - do a sweep to see what the competition is charging. No one is going to buy your $7 book if they can get it down the block for $1.
The price of an e-book is a lot less than the price that we're charging for a hardcover book. It's about the same as we charge for a paperback. And that means a different revenue stream.
Interestingly, the oil companies know very well that in less than 30 years they will not only be charging very high prices, but that they will be uncompetitive with renewables.
