It's super-simple to post your books. Once you upload, they take care of the heavy lifting for you. And it's a lot less of a formatting headache than Smashwords used to be.

Last year, I moved most of my e-books out of KU (for many reasons) and published wide on Draft2Digital. Momentum can be slow, but if you use the Books2Read universal links and use that in your advertising and promotions, it puts other options before the reader. My sales aren't huge, but they are steadily increasing, particularly with Apple.

There is so much work to do at the start of publishing, but I promise you once it is all done it does get easier. Take little bites out of the large meal and eventually you will get it all done. But you also don't have to do it all, if you are happy with amazon, you can stay there and nowhere else and you will be fine.

Bookbub is a great place and the featured deals are fantastic, if you can get one. They are very hard to get and really expensive. I have never been successful.

Unfortunately, when you're chronically ill, EVERYTHING takes too much time and energy, so I haven't tried anything beyond Amazon except B&N, and that was a decade ago - I'd be surprised if I even had an account still, and it never sold a book.

But I read that advertising/marketing platforms like BookBub prefer books which are wide, because their customers do, and know that's probably part of never getting a Featured Deal (I find it ironic that an expensive outlet won't even take my money!).

One of these days, when the last volume in my mainstream trilogy is finished writing, I will be able to dedicate my daily spoonful of energy to the marketing. Meanwhile, Amazon has been my salvation, even though it's not perfect, and has been where any sales have occurred.

There is a real barrier to being self-published for those of us who have chosen the control of being indie, but don't have the resources that are required when you have to do everything yourself. Not complaining - it's still far better than the traditional-publishing submission system - but what I wouldn't give for some of my former ability!
