They haven't really reached (2) in any market besides books. As dominant as Amazon is, Wal-Mart still towers over them for just about every product category that isn't printed on paper. I'd argue (3) shouldn't read raise prices - that isn't really Amazon's MO, (3) should read "leverage their de facto monopoly to squeeze suppliers for all they've got, Wal-Mart style". This is certainly happening in books.
