Thanks to kobirulali's post (http://www.hotukdeals.com/item/401948/nintendo-wii-incl-wii-sports-145-as/showthread.php?t=401948) I popped into the Asda (Hatfield) store last night and bought the Wii console for £145.
As I needed a second remote, I also purchased the Wii Play for £29. To my surprise, I received £19 discount at the till! Total price £155.
Not sure if this can be done ONLINE?
