Today is the first (and only) time Ole And Zac And The Port Of Tumbattle will be offered free on Kindle. Without the benefit of reviews sales will be difficult, and in the 3 hours since the promo went live there have been precisely 3 sales! Two in the US (including India) and one in the UK.
Tomorrow Stags! will be free (for 3 days), whilst the Tumbattle promotion lasts 5 days. I will keep you posted on progress.
