If someone expects me to pay more for an e-book than for a paper copy, I move on. Plenty of books other books to choose from. Just because a publisher charges more for the e-book than for the paper book doesn't mean they have actually set the price at the level which gives them the maximum return. Publishers can make mistakes.
