Marks are having a clearance of old electrical goodies stock at the moment. At my local (hedge end) they had a drawer full of 2gb and 4gb ipod shuffles (sealed brand new) 2009 models for the above stated prices.
Great price - similar to morrisons a while back.
Dont know if its all stores but definately hedge end. Various colours available.
