I think you overestimate the physical cost of books. From http://michaelhyatt.com/why-do-ebooks-cost-so-much.html, "Second, physical manufacturing and distribution expenses cost less than you think. Some people assume that these two items represent the bulk of a book’s costs. They don’t. Together, they account for about 12% of a physical book’s retail price."
Aye. I'm publishing a book soon. By using Lightning Source to list on Barnes and Noble, I can make amazon discount my book, which doesn't affect my createspace royalty. I should be able to have the book sell at $26, and keep $21.
Aaron Shepherd's Plan B (an update to POD for profit).
Selling to B and N with a 55% discount from lightning source should make the books appear with a 40% discount off the list price. Amazon generally matches those discounts.
The list price will be $44. 44 * 0.6 = 26.4
Using the Createspace royalty calculator, $44 with a 300 page book produces a royalty of ~$22.
Amazon discount don't reduce Createspace royalties. I may be overlooking something, or some part of the plan might fail of course.
Strangely, that's not what the publishing industry says when they raise the prices of physical books. Then, the primary determiner of prices is the cost of paper.
Varies based upon selling price, type of book, etc. Wide variation on quality and scale vs size. page count. etc. printing something != something quality. and copy 1 = not equal 1/4000 or 4000 copies. So, sell thru rate matters (how much of the run you sell). The costs are borne by someone.
Too bad they don't have a source of any kind. So many of these kind of articles are written by someone with a position in the fight, and then they just cite "stuff they know".
