You have to have monopoly power to do so by the tactics at issue (limiting consumer availability and manipulating retail prices) since in a market with effective competition that does more to direct sales of the product to competing retailers than to hurt the total volume sold by the publisher.
You just need more loyal customers. My first stop is Amazon. But I would not say I am loyal to Amazon above all else. If I really wanted something and they didn't have it, then I'd move on the next stop. In this case (that book about Amazon) I'd head on over to Barnes & Noble and pay just $0.31 more to order it there. No big deal.
