GASP the publishers want to make profits from their publishing business. This is ABSURD!
At the expense of retailers and consumers via a practice that brings to mind the days of Ma Bell, Standard oil, or any other monopoly except in this case competitors unified to drive a cost up, which is probably the only reason this isn't illegal. (And maybe it could be...)
The mark up on paper books is usually in the range of 40%. So a $10 paperback nets the publisher $6.
A $10 ebook nets them... oh wait... $7 (since the retailer now gets a fixed 30% of the retail price and not a fixed or negotiated cost), and the retailer is forbidden to alter the price of the ebook. Who the f is anyone to tell a retailer what they can and cannot sell their merchandise for?
If the retailer wants to sell a paper back on sale for $8, the publisher still gets... $6.
If the retailer wants to sell an ebook on sale for $8... the publisher still gets... oh... $7.
The only people who lose are the retailer and consumer. Now if you want to get to the real dirty truth of this issue, it probably cost the publisher about $3 to print and distribute the paperback in the example above including buy back fees. (that's very generous, it is probably much less, and most of the major publishers will accept returns on excess inventory after a first run, which is where bargain books come from later as they are redistributed at a discounted rate to clear the inventory. Buy backs do add to the cost factor.)
So a publisher makes about a 50-70% profit on a paper book depending on their specific agreement with a retailer for buy backs. On an ebook, it's more like 70%-95% profit because there is no inventory, printing, buy backs, returns, damages, shipping, etc. (Most authors get very small royalties or advances unless their big named people).
So sure, a publisher is entitled to make more money, but pushing upwards of 45% more profits for ebooks is absurd.
The consumer is also buying a device to read the books on, a cost they pay and not the publisher. It's just evil and stifles both innovation and reading. If the publishing industry wants to see a Napster for books bite them in the ass, this is a good way to encourage people to try.
