Fighting with Amazon's very annoying Kindle Create program appears to have paid off. I received the proof copy of the paperback version today and it looks fine.
The only thing that caught me off guard was Amazon's default 9 x 6 format is quite large for a paperback (at least in the UK).
I've flicked through it and it looks to have come out fine, so I've just submitted it on Amazon. If everything goes to plan, the print version should be up for pre-order as soon as it's approved, and the book will go live on the 14th Nov alongside the ebook version.
Now the bad news.
Mass market paperbacks rely on big batch production to keep the costs low. For smaller, self-published authors like me, we have to use Amazon's Print-on-demand service. This does seem cheaper than I remember, but does bump the costs up. When I was with eXcessica, I think the price of the print version was around $20. I think that's a little high, so I've set it at $15.99. This is still high for a paperback, but any lower and I'm pretty much getting nothing. (With this I get about a third, which is enough that I don't feel like I'm working for Amazon for free.)
So, yep, the print versions are still a little pricy, but the option is there for people that want it.
(Hopefully, I'm still waiting for final approval, but as the ebook is already up for pre-order, it should in theory be okay.)
