"Can someone just disrupt these folks out of existence already?" Charging people different pricing in different locations or at different times or to different buyers is not in itself wrong (although it can be). Restaurants regularly give "senior" discounts, "ladies for free" as well as offer discounts if you dine at different times. Is that fair to me if I only dine on Saturday night? (Or what they do by having special menus for New Years Eve or other occasions where the price is higher than on normal nights). It's not about fair. Companies do what they have to do in order to make a profit and in some cases that involves legally charging different buyers different prices. I'm able to make a better deal, for example, at a car dealer because presumably I can negotiate better than some other people. As a result the car dealer trying to rip off a newbie subsidizes my sale and allows them to charge me less (so they can meet their manufacturer volume requirements) If the companies could charge more overseas perhaps they would. In any case the volume in sales they make offsets the price that they have to charge in the US as well. It's entirely possible that if they tried to sell at the higher price overseas they would have less total volume manufactured and as a result the price in the US would be higher than it is. I drive a fairly expensive car. If the manufacturer wants to price it at a lower cost in some new market overseas and they can lower their costs doing so and sell me my next car at a lower price (but not as low as overseas) that's fine with me. I don't know and I'm not saying this is what's happening with textbooks. I am merely pointing out that the constant use of "disrupt" doesn't always take into account the reasons why things are the way they are.
