Unfortunately I only offer refunds on the free version. Maybe try selling it on EBay as a collector's item. The beauty of digital is you can put condition as "like new". So, it has been an interesting experiment so far. I only advertized it as being free here in my Wattpad profile, and on my Amazon profile, and in an old post that nobody will see on a FB forum. I also entered it into Amazon's KDP Select, but no idea if they promote it. So far I've 'sold' 18 copies, plus someone bought the flash of light and dark paperback! It's worth thinking about to put out a cheap book and follow up with a more expensive one, then give away the cheap one. It's the closest I've come to any sort of marketing; I'll let you know when I get the final figures in.
