I was at my local Toys-R-Us in Ontario, Ohio tonight and took a look at the NXT inventory. I was absolutely amazed to see that they had the NXT 1.0 on the shelf marked for $144.99!! Incredibly it was not a sale, it was the regular price. Right beside it was the NXT 2.0 and it was marked at $299.99.
I checked on the TRU online store and they are not selling the 1.0 anymore. Then I checked out S@H and they are selling just the brick for $144.99.
So if you want to stock up on parts, sensors and a NXT brick or two, check out your TRU quick because I imagine that once they are gone, you will be out of luck.
