There was about $1000 fixed cost that I need to recuperate (design, marketing, etc...), beyond that, the only cost is transaction fees for credit card/paypal processing. Which I believe is 3% or something like that. Hosting and everything else is negligible. The rest goes to GiveDirectly.org - You can always just get the book for free and donate directly, if you don't trust me :)
