I do think some of the pricing is crazy. I have bought a couple of paperbacks just because the kindle was priced more than the book! I note that Amazon sometimes posts a notice that the price was set by the publisher and not Amazon. (Must be tired of the complaints.)

Anyway, I also donated some books that I didn't replace, but that I see are available in Kindle. All of the old Rex Stout novels are finally available on Kindle. So, if I want to reread my old favorites, I know they are there but they don't have to be physically there in the house. I actually did check all the books as I decluttered and only donated the ones I knew I could replace. And I check the free books, too, since the Kindle can handle those.
