Just for the record: You don't just get a PDF. You get a real e-book too.
WHatever. you are missing the point. Copying ebooks cost no money at all, there's no reason an ebook should cost that much in the first place. Dead Tree books were heavily dependent on material and inventory costs, ebooks do not suffer any of those yet they are still sold at similar pricing while they should be at least 90% cheaper, if you just kept the margin at the same level. It's pure profit for the publisher.
Well, sure, in the world where the only costs that sales price needed to cover were the marginal costs of the current copy, and not some share of the fixed costs of the content.

"Were"? Physical books are still around, you know. Also, those costs are partially marketing costs -- having the book printed and out on the shelf in a bookstore is a form of marketing. While they may not have the printing and inventory costs of physical books, ebooks definitely have marketing costs and, because of the low barriers to entry in the market compared to the market for physical books, arguably have more competing noise that their marketing is trying to be heard over. There's a cost of dealing with it, and the sales price of the books has to pay for it for selling the books to be a profitable business.
