One of my favorites to stock in the gift closet is marked down again, today—pick up Castle: A Three-Dimensional Interactive Adventure for just $2.95 (free Prime shipping, or Super Saver Shipping eligible) today at Amazon.
Please note that this is a book for ages 9+, and perfect for those sci-fi and fantasy lovers out there. It is not, however, a pop-up book for little kids. But to grab a gorgeous $20 book for under $3? That’s worth tucking away for a few years, even.
