Anyone who’s ever bought a book in North America has seen the dual pricing model displayed in the corner of the dust jacket: one price for American buyers, and a considerably higher one for Canadians. The reason for the discrepancy, of course, is that the Canadian dollar has traditionally been far weaker than the greenback. But the American dollar is plummeting these days, and with Canada’s loonie now worth upwards of 90 U.S. cents, consumers north of the border are crying foul over having to pay a 30-40% premium on books.
