For another perspective on the printing of prices on books in several currencies, Jaime Tolbert of Baja Books and Maps, Los Cabos, Baja California Sur, Mexico, writes:
As an English-language book distributor in Mexico who imports 90% of
our titles from the U.S. and pays a 30% importation fee, I have long
urged U.S. publishers to cease placing prices on book covers. We must
pass our importation costs on to our accounts and ultimately the
consumer so our suggested retail is usually higher than the price
printed on the book. This coupled with dual pricing in both dollars and
pesos causes a strange kind of sticker shock as store clerks are often
told, "I thought everything was cheaper in Mexico."
Of course, we must adjust our suggested retail when there is significant change in the dollar/peso exchange rate.
In a truly worldwide economy, U.S. prices have no place on book jackets.
