This offer is on until the end of November - currently if you buy an HP laptop you can claim £50 cashback on it directly from HP. Ebuyer are currently selling a fairly good spec HP laptop for £219.99, so this works out at less than £170 including the money you get back.

Laptop specs look great for the money - 4GB RAM, 500GB hard drive and a dual core processor, plus the laptop itself is pretty light.

Details of how to claim the cashback are on the Ebuyer page I've posted.
