Popped into my local argos (Durham City Centre) and despite it not showing in the catalogue, behind the collection points they had Wii's IN STOCK and DISPLAYED at a MANAGERS SPECIAL, only £159.99 instead of £179.99 so thats £20 off retail and if you have them in your local store you're sorted.
Bargain me thinks, shame I already have one.
Although most places have them in stock now, this was the first one I had seen reduced without codes/coupons and vouchers :D
Let me know if you find any in your local store.
Durham had 3 left on show at midday today.
First main deal so sorry about the formatting of the post :s
