Just popped into a Leicester Tesco and took the last 1 TB Seagate Expansions 3.5in external hard drive with the security pack included.
This drive has been posted before at £59.99, and some people found them at £49.99 in April but that has expired. It was marked discounted on the shelf at £49.99 and rang through the tills at that. Therefore if you can find one in store, it will probably be the same. it's £65.97 online
I also notice online the Hitachi 1TB is £59.99... that's not bad.
