Argos have the Monsters University Sulley Radio Controlled Truck back in stock and on sale for £7.49 reduced from £29.99. It's still not available for home delivery so you'll have to collect in store but there was great stock availability at the post codes I tried. The Sulley mask has the same reductions, and is in stock, but is also available for home delivery.
This simple function remote control Monster Truck drives forwards and backwards on giant Monster Truck tyres. In true monster style, the mouth on the front of the truck opens and closes with chomping action as it moves along.
This toy was inspired and designed just for Sulley, and there's space on the back for friends - we know Sulley always makes room for his friends.
The mask is super cool too as it lets you control the movements as his eyebrows and the mouth moves as you talk.
And remember that you can grab the Disney Personalised Photo Height Chart to your basket for 99p too, since you're making the trip.
