OK so there's going to be people that hate Norton products, but for those that don't - This is an absolute steal!
You get to put it on 3 machines for less than 25 quid! - it normally costs double that!
Norton anti virus costs £39.99 on it's own - you get it included with Internet Security and personal firewall, antispyware, antiphishing, and identity safe.
This was in the Chester store, though I imagine it's nationwide as they were correctly stickered up and the shelf labels confirmed the price to be £24.99.
Love it or loathe it, a year's cover for £8.33 per machine is pretty good going!
