Edit: Sorry folks, it appears that this deal is no longer available   I received notice of it and I can confirm it was live because I personally ordered the colour sensor, some cables and other parts which were all processed at the discounted price… Guess it was a (very) short term deal (or mistake). 

Quick!  These deals may not last long, but the NXT set (and some other items) are in sale at Lego Shop at Home (at least for Canada!). If you are looking to buy a NXT or add to your collection, this may be your chance! Here are some items:

(Note - all prices are quoted in Canadian dollars)

• NXT set $249 (from $349)
• converter cables and connector cables down to $9.99 (from $14.99)
• Rechargable battery $49.99 (from $69.99)
• Compass sensor $46.99 (from $59.99)
• Colour sensor $46.99 (from $59.99)
• Note -the Compass sensor is listed on hitechnic.com for $46.99 (and the colour sensor may be the same once the price is listed) - so these two may not be such a hot deal.

There is a total of 93 items including those listed above.  Looks like I might just go after that colour sensor now!  Not sure how long the sale will be on…  http://shop.lego.com/SalesAndDeals/Default.aspx?va=1
