Add Kindle price for non-found books? (or all books?)

[brianpipa]

We have easy access to the Kindle price. Would that be worth adding to the non-found book in KU searches? Not sure. Maybe? Would allow a user to easily see how much it costs and makes it easy to decide if they want to go buy it. Could also add price from other places too like Google Play, etc. but those prices would take more work to get.
