Found a cross cutter paper shredder for £12.00 at the Morrisons in Sutton (Surrey).
Shreds upto 5 papers at one time.
It did'nt have the CD slot . Please check whether it accepts staples.
This deal is for those who have missed out on the Sainsbury offer but still one a cheap shredder for disposing of unwanted mail (lucky I got mine in time from Sainsbury).
