Query: Someone explain this

I haven't yet read this novel - and of course I know I should not be "reviewing" it... But someone please explain to me - how can the Kindle version of a book - any book - be MORE expensive than the hard copy version of the same? If publishers, Amazon, or anyone, really expects those of us who have bought a Kindle to follow up our purchases with actual books, they are going to have to do better than this.
