Author here. I know - I did have a feeling of guilt applying a price to it but honestly, I've been putting a lot of work into it at the expense of other projects (I do free youtube tutorials too) and was hoping the price would help implicitly identify that. Is there a specific reason you say it's a shame it has a price?
