I found a Lego City Dozer in Tesco marked on shelf as 1/2 price; was £29.99, now £14.99
Realistically you'd never pay £30 for it! Amazon & Lego.com are selling it @ the £20 price point, but still a bargain for £15!
This is it on LEGO.com:http://shop.lego.com/product/?p=7685&LangId=2057&ShipTo=UK
I got mine in the Bristol Eastville store, and they had one left on the shelf.
Show me a person who doesn't like LEGO, and I shall show you a fool.
