Do you buy a lot of e-books or do you usually look for free ones first? Do you find that there is a good selection of free ones on most topics that interest you? When or if you do by ebooks, how much are you willing to pay for them? Many are offered at reasonable prices, but then again I've seen some that are quite a bit more. Are you willing to pay the price of a "real" book to buy an ebook? Does it depend on the topic? What's the most you'd pay for one and what would cause you to pay more than usual?
