I mean, it should be a good book, but you literally name it the zero-budget gamedev marketing manual and then make the book paid. I don't wanna make fun of your work, but it was a funny thing

There's a free Lite version, if that's helpful. But also feel it's fairly priced given the pricing of most resource/academic style books of this nature.
Zero-budget refers to the tactics and principles involved in marketing a game whilst self-publishing with no marketing budget, and not the book itself if that makes sense.
If the price is a barrier for you, please get in touch, though - can try to help you out here.
Cheers!
