This saturday and sunday PC World in Watford are trying to clear out some old model laptops. Ex-display mostly. Speaking to one of the staff it seems they are taking about £50 off most of them. Plus abuse their PC Performance, tell them you'll take it if they give you a discount then cancel it when you get home. That trick works on all their Laptops and Desktops, it got me an extra £30 off.
This is NOT company wide as far as I know just in the Watford branch.
