I purchased a promo stack from Free Booksy, which is set to begin on June 24th. This promo stack lasts for a week. I made my book free for the maximum of 5 days, i.e. until June 29th. Should I drop the paperback on June 27th or June 29th? Is there anything magic about dropping it exactly 3 days after the Kindle download, or would the extra 2 days of "just download" help me get more attention?
The book is 4th of July themed so in a way dropping the paperback earlier ensures people will get it ordered in time for the holiday.
