Aria also has a good offer on this hard drive, but the advantage of Scan is that the drive definitely comes with a three year warranty rather than 1 year.
This drive is on today only at £76.36 which for some people can be had delivered. To get it at that price buy it via the today only part of Scan's website or:https://secure.scan.co.uk/aspnet/Shop/AddToBasket.aspx?WebProductId=888021
Peculiarly the standard page for this drive which is at £79.77http://www.scan.co.uk/Product.aspx?ProductId=23170
seems to result in free postage regardless of whether you have free postage with Scan which is still a decent deal.
EDIT: Apparently the free delivery is an official offer and applies to any order including the drive; it's mentioned on Scan's home page but it doesn't seem to combine with the "Today Only" price
