Perks of self-publishing is that I can decide the price of my book myself. I believe that more people will buy my book if it is cheaper and hopefully everyone will like the book and tell their friends that this book is both good and cheap. It's a win win.

I can price my book so that when someone buys it, after taxes and all that I can at least buy myself a coffee while working on the next project. I see it as a "Thank you for helping me, here's a coffee".

I understand that books from larger publishing houses are more expensive because there are more people that needs a coffee to some extent there's just too large of a margin or too many coffees that needs to be handed out.

Based on how many copies I've sold from self-publishing I've been able to get myself more than a coffee, but the individuals that bought the book didn't have to suffer too much economically as I don't price the book in the range of a new mobile phone.
