Actually the book as sold exceedingly well and there have already been a large number of downloads.
My cousin sister's boutique functions exceptionally well also. It's not only popular among college girls, but a lot of fat rich snobbish aunties also shop there regularly. Besides ,popularity doesn't mean something's not shit . Justin bieber music etc, all very popular, but shit. Besides, if the book is being sold exceedingly well , there's no need to advertise it , is there?
