We definitely have sales a few times a year at http://www.instarbooks.com, if you want to sign up. The print book is a huge tome and costs $25, but you also get the ebook free when you buy the print book plus all of the games. We feel that $10 is a fair price because it is cheaper than almost all the ebooks available on Amazon and Kobo, but of course more expensive than something self-published or which you would be able to download via subscription, which perhaps has not been edited or gone through a publication process to work out some of the kinks. Plus, you get all the games as well when you buy this ebook from itch.
