I received an email from Draft2Digital today that says it is no longer free to use; there will be a $20 activation fee for new accounts.
There is also an annual maintenance fee of $12 if your annual earnings (after Draft2Digital's commission) is less than $100.
This seems like a significant change that will probably push many authors back to Amazon.
I wonder what the disengagement process with Draft2Digital would be? It is entangled with at least a couple of dozen external accounts. If you close your Draft2Digital account, do they just keep all the future proceeds from your books on Apple, Barnes & Noble, Kobo, and all the rest?
