Tyco Airblade All Terrain R/C Vehicle - £29.99 instore (£40 Off) Toys R Us instore only.
I just got one of these from Cardiff Bay Toys R Us, reduced from £69.99 to £29.99. They currently have them in Argos priced at £69, so it looks like a good deal. Instore only as the website suggests that they are out of stock. they had at least half a dozen on the shelves. The offer appears to be nationwide as it's on their website, but check availability at your local store before making a long trip.
