I understand the concept of supply and demand but they should understand that in todays world, people need a little more encouragement to fork out cash for books... Even if they are needed for college... Most people buy used to save on the crazy costs...
Even regular ebooks shouldn't be priced more than 2.50USD internationally (no matter who the author is) Amazon etc wont go bankrupt or even lose money if they lowered their fees just a tad!
