We authors whether we go the traditional or the self-published route, are in it together. I feel we should support each other in a world that is indifferent and possibly even increasingly openly hostile to books. Books are wonderful things and although now in my old age I have difficulty with the small print in some books) (I do resort to ebooks as I can make the font bigger) However, I can still buy the large print books.
What you end up getting depends on three things: the price
you charge, the cost of manufacturing your book and whether or not you choose
to have it distributed.
You will always earn more on Lulu than you would on any
other sales channel. If your book is distributed the distributor takes 50 % of
the cover price. The cost of manufacturing the book, and Lulu’s cut, is
deducted from the remaining 50 % and what remains is what you get.
It will always be better to sell your books through Lulu, if
you can. And it will always be better to charge as much as you can for as few
pages as you can. However, having said that, this is not always practical.
