In what I like to think of as the “cock block” Amazon has said to self published authors that only those POD books that use Amazon’s POD service will be for sale through Amazon. Before, if you were a POD, you could have your books fulfilled by Lulu.com or any other POD service. Not any more.
I wonder what effect, if any, that has on epublishers who use a POD service.
