Just found this on scan.co.uk after their today only offer expired. Seems to be the cheapest 1TB external drive around and is general availability.
Free delivery for AVForum and hexus forum members.
Price modified to reflect Today Only offer, will change it tomorrow after 12.
Use the link: http://www.scan.co.uk/todayonly/#2
to go to the today only page.
All rep to the two users below who found it :)
