I must say, you and I have a rather different take on the Amazon/Macmillan situation. What Macmillan wants under the agency program is for Amazon to no longer serve as a retailer (by setting prices) but to serve as a sales agent. Macmillan would then set the prices, and those prices would presumably be the same everywhere (since the other retailers will presumably have to follow the same agreement, or face the same "windowing" that Macmillan said they would do with their e-books at Amazon if Amazon didn't agree). Amazon has revolutionized the e-book market through their willingness to take a loss...not the publisher's loss, and not the author's loss. Authors may be paid based on the list price (let's say, 25 pounds) or the amounts received (which would be 12.50 in Amazon's model). To my knowledge, it would be an unusual contract for an author to be paid on the sale price, rather than the list or wholesale price (which are the common two options). The agency model results in less money for authors, even ignoring the question of volume. It also creates a non-dynamic market, in which you won't see sale price variations (which stimulate sales). I want to be clear about something, though. You are saying that you don't want people to get the books from Amazon? I recently sent a post out to my readers alerting them to the ability to get the second book for free from Amazon. I'd be happy to amend that. I will add a link to this post, regardless. I do respect author's wishes, and if you aren't comfortable with people getting the books that way, I'll let them know.
