Note my %'s may be off slightly but it's irrelevant to the question. If their book sales are similar to their Android App Store then as the publisher you get whichever is more between. "20 percent of list price and 70 percent of sale price" So Amazon can sell it for whatever it wants but will owe you 20% of what you listed the book at. It gives them a very wide margin to play with.
