Amazon has a sale right now on the NXT kit.  And, it qualifies for the Free Super Saver Shipping, so you only pay the $203.62 price.   This is one of the cheapest prices I’ve seen for the NXT kit.  And the free shipping… hard to beat.

This would be a great time to buy the One Kit Wonders book and a new NXT kit for you, or your child (or both!).  Remember… every project in the One Kit Wonders book can be built with a single retail MINDSTORMS NXT kit.  Of course, I’m partial to Chapter 7 myself.  :)
