In the news, there are reports about lawsuits against Apple for colluding with publishers to keep prices artificially high and to prevent other sellers from offering the book for less.
I recently purchased the ebook Stolen Continents by Ronald Wright from Kobo books. $18! Yikes. But I really wanted it. Later I checked the price of the paper version on the Chapters/Indigo website. Surprise! Regular price is $18 (the same) and it was on sale for $13.68.
The publisher is Penguin, one of the ones mentioned in the lawsuit.
