I have just picked this up, seems the best 1.5TB deal at the moment that has free delivery and plenty of instore stock. All my local stores (braintree, chelmsford, and colchester) have stock.
Follow the link, add to basket, apply 5HD for 5% off, don't forget quidco for a further 3% bringing this down to around £78 delivered. Only some delivery slots are free but I just collected mine.
My IOMEGA 320GB portable drive has been dropped knocked and all sorts but till functions perfectly and passes all HDD diagnostics. Hopefully this IOMEGA is just as good quality.
I forgot to add, this might be store specific, but the Colchester store gave me a £5 off my next £50 spend valid 12-31 March.
