Walmart offers The Art of Fire Emblem: Awakening Hardback Book for $21.75. Choose in-store pickup to dodge the $5.99 shipping fee. (Amazon charges the same price via Prime shipping.) That's the lowest price we could find by $5. It contains illustrations, storyboards, profiles, and the entire script from the popular 3DS game.

Of note, Walmart lists this as a paperback, but the publisher's website indicates that it is indeed a hardback.
