This has probably been brought up before, but I am not able to find any of the threads and I've not seen any official thoughts from Amazon.
I think self-publishers should have a way to have their own books delivered to them from Amazon for free.
I realize that, as a self-publisher, I have access to all the book files, however, I feel it would be extremely helpful to confirm that all features of the book made it through the conversion process. Additionally, if I make highlights in my own book, or others make highlights, I might like to be able to see them and have them sync across multiple devices.
As I see it, currently, to do this I would have to purchase my own books.
You can download the converted mobi file at Step 7 for free and either side load it into your own Kindle or use the downloadable emulator to see how your book will look in the various Kindles--or, preferably, do both.
There's nothing wrong with buying your own book! Most old-timers do so with every new book. It gives you a first sale and that initial ranking. And assuming you are getting 70% royalties, you get most of your purchase price back, so you're only spending a dollar or two. Isn't it worth it?
I sideload my MOBI files to my iPad or Kindle before submitting them to Amazon. What really interests me the most is to see what others are highlighting and noting.
Even the MOBI files, though, are converted to a more advanced Amazon format. I write everything using Sigil, as EPUBs, and I have pieces of code that render the correct way with the MOBI, but not using the original EPUB in, say, iBooks on my iPad.
Unfortunately, all my work is in the restoration of public domain documents, so I would only recover 35% of my own money. I've restored roughly 90 books ranging from $1-$4 (well, one $10 and one $15, but those are collections of works) , so it would be a significant amount of money.
