As it relates to ebooks, Draft2Digital was still the best choice in getting our ebooks to non-Amazon storefronts even though they use the royalty sharing model.
For what it’s worth, though, their model is superior to most because they’ll actually help you with formatting. We produced our own EPUBs for distribution but if you are not sure how to do this, you can upload a text document to this team and they’ll do the work for you. For an independent author, they can also handle distribution to Amazon, giving you a single place to manage your distribution.
You can also schedule promotional pricing for your ebooks to temporarily drop the price of your books. In short, it gives you the most flexibility and they have a great support team. It’s 100% worth checking out.
