Saw this Lego set in Asda Tamworth today (Sat), upstairs, not with the other Lego but on the end of an aisle amongst other toy reductions including a couple of Lego Ninjago sets. Says reduced from £23 to £11.50 but normal price of this set is £34.99. There were seven left after I got one.
Absolute bargain! Not sure if national.
