No dude, your books are not so incredible that people will buy them no matter what the price. There may be a few people who are like that, but most aren't. Price matters in entertainment. Turns out, when you make something cheap enough so that people don't need to think about spending the money and even more so they feel like they are getting a "Great deal" they'll spend very freely.
Steam has figured this out with videogames and siphons tons of money out of people's pockets, and has people thank them for doing it. People get drawn in by the "savings" of the sales and spend tons. I should know, I'm one of them. Not only do I have games I haven't played, I have games I haven't installed. I see something that I'm interested in that is a good price and I say "Oh man, I should get that," and I do. If they are more expensive, I think about it more, I wait until I really want a new game, I go and replay something I already enjoy.
Cheaper books will lead to bibliophiles just collecting the things. I know my mom would. You get them cheap enough and she'll drop hundreds a month on stuff she'll never read, just because she wants to have it.
Authors/publishers/developers/etc need to get over this idea of their digital goods being "worth" a certain amount. No, you need to figure out what you need to do to maximize your profits since there is zero per unit cost. Usually, that is going to mean selling cheap, but selling lots.
