This for some reason this is a bit of a rare set and argos have knocked £15 off bringing the price down to £34.99.
Next cheapest Lego Shop at £44.99.
Currently out of stock for home delivery but available for store pickup at a number of stores.
My boys have collected pretty much the whole of Lego City and Indiana Jones so have always held off from the Star Wars Lego which they love, but this would make a good introduction. Hope someone finds it useful, especially as its rare for anything more than £5 to be knocked off a lego set.
They also have a few pounds off of the Lego Tanker:http://www.argos.co.uk/static/Product/partNumber/3881707/Trail/searchtext%3ELEGO+TANKER.htm
