A Kindle dilemma

Just checked Amazon for the third book in the Raichev series. It's newly out in paperback (June). I can buy it in trade paperback for $10.19 or on the Kindle for $9.99. Hmmm... this is the first time I've faced this dilemma on which to buy. Usually Kindle is significantly cheaper. Why is the Kindle price so high? My guess is that the Kindle price is still based upon the hardback price. I don't want to read it right away (that's a good way to ruin a series -- read them too close together) so I don't need to download it to the Kindle now. I guess I'll end up buying it in paperback for just a little more. I think I might want to own the paper version of these books.
