The launch of Grim Tales at the start of the month wasn't that great and resulted in no sales despite having some interest.
The PDF version of the book on Gumroad launched with a pay-what-you-want model starting at $1 - so today I reduced that to $0.
I'm more interested in people reading the book than I am earning any money from it.
Who knows, maybe reading the ebook will lead people to buying the paperback (which is the better way to read IMO).
