Bit of a (possibly) daft question now.
What are your preferred sales and marketing channels? The ones I have inherited are Skoobebooks (Preferred for physical), Smashwords, Createspace, and Kindle Direct Publishing.
Now, Skoobebooks and Createspace are for the physical books, and have the ability to produce and ship books in Europe and the USA at the very least.
Meanwhile, Smaswords and Kindle Direct Publishing (obviously) are for eBooks. With Smashwords distributing books all over the major electronic retailers, including iTunes Book Store, and places like Barnes & Noble.
Which of these formats would you use on an exclusive release, if you were or do? Are you a paper publisher, or an electronic publisher? Do you combine?
How do you generate your sales? What is your preferred form of marketing? If you have a limited (or zero) budget, how would you advertise, without giving the best bits of the book away?
