There's a clearance on several Medion laptop and desktop PCs at Aldi starting today, link here:http://www.aldi.co.uk/uk/html/offers/15867.htm
However, not listed but plenty of stock in my local store (Shirley, Solihull) was a small/light 500Gb 2.5" external HDD drive with £20 knocked off. 3 year warranty too! They also had full size 1Tb drives for £79.99 though no reduction claimed and I don't think that's such a good deal.
There's limited stock on these deals so be quick if you want one.
PS Just checked in my local Tesco and they want up to £89.99 for the same size 2.5" HDD!
