To Prime or Not to Prime

As anyone who knows me knows, Sullivan's War: Book I - All Good Men Serve the Devil is being released Friday, January 20. So, do I enter it in the Amazon prime program?

My answer, at least for now, is "no." Why not?

I have entered my other ebooks in the Amazon Prime Program and I am, for the most part, happy with the results. But I do wonder about something. Do Kindle owners peruse the list of ebooks and mentally take note of the Prime books they're interested in with the idea of waiting until the author makes them free? I simply don't know. And I don't want sales of Book I to suffer if this is the case. I know there is an argument that making the first book of a series free increases sales on the other books but since I do not yet have the others released, I will not benefit from this for another couple of months.

I do, however, have Sullivan's War: Prologue - Sergeant Riley's Account in the Prime program. I hope that I can use the free promo days for this book to increase the visibility of the series and entice readers to purchase Book I. I also want to make Book I available on B&N and give that another go. Perhaps having a longer work will help sales at that store (I understand short stories just don't sell as well as longer works.)

When I have Book II ready for publication I will reevaluate this decision but for now I think it is the right move. Does anyone who's released series have any other tips? I'd like to do everything I can to make Sullivan's War a success!
