Buy the super cool LEGO Mindstorms NXT 2.0 this weekend (or while quantities last) for $349.95, and Chapters will give you a $70 credit to buy anything when you make a future purchase.
Reviewed as "amazing", this set will give you everything you need to build and program your own robot, so obviously, you can take over the world (or alternatively, just have fun with it). The robot can perform many different functions and even has two touch sensors so the robot can "feel". Not only can the robot feel, it has a sensor to see and an NXT micro-computer to think. An included software CD gives you building and programming challenges and complete step-by-step building instructions and a programming guide.
This item is something my kids and my husband would thank me profusely for. My techie husband would love to teach the kids to program and this makes it completely fun. I can justify the price to myself because I can use the credit to get what I want later from Chapters!
Reviews on the LEGO website include "best present ever", "love it", "challenging in a good way", "infinite possibilities" and "LEGO you've out done yourself".
Shipping is not free for this item, but for me it was only $6.
