These books are usually updated yearly too, and they aren't normally sold at retailers. You'd need to go through the trouble of republishing yearly and there would be others reviewing the content each update. So it's reasonable textbooks are expensive. However, since your customers are forced to buy specific books instead of choosing their own, you can set the price as high as you wish. In healthy markets there is competition among sellers. The goal is to sell better products than your competitors, but there comes a point where customers will choose cheaper products even if they're worse just because your products are too expensive. This keeps prices low in the market. However, if you remove the power of choice from customers, you can set the price as high as you want since there is no competition.
Textbooks should be expensive, but not this expensive.
