I'm quite new to this whole e-reader/e-book thing. Anyway was just browsing some websites and looking at possible purchases, and along the way I quite often noticed that sometimes the e-books would be a couple of dollars more than the paperback version.
How the jeepers does that work? There is no printing, paper, transport and so on involved with an e-book, so how can it be more expensive.
Can someone please explain what I am missing?

As a result I didn't purchase the e-book or the paperback version.
