I simply looked at the range of pricing e-books, considered that I am unknown and priced it below a fiver. I thought about going the way of the 99p pricing but I didn't feel that was right for my book. I wrote my book as a challenge more than anything and as yet have done almost nothing as regards advertising or promoting yet I have seen a steady trickle from the digital book shelf purely through the 'pass it on' principle. My achievement has been to write my three books and see them published. Although it's only in the digital world I am still published. My promotion push will come soon, most likely with my next two books now I have had an experience of writing and trawling the publishing world then maybe my books will be priced all the way up to a fiver.
