Frozen: A Pop-Up Adventure Book at Amazon for $11.20 + tax & free ship with Prime
I had to get this for my daughter after seeing it at Barnes & Noble. This is one of the most impressive pop-up books I've ever seen. Very large and very intricate. Amazon usually has it for around $22, so this is a pretty good deal.
If you have other books to buy, don't forget about the $5 off $15 coupon for books sold by Amazon. Code: GIFTBOOK17
