Saw this in sainsburys wednesday and bought one so went in again yesterday and asked if any more, and there were 4 more out the back so grabbed another.
Cant see why its not everywhere.
Also had the smaller 1tb seagate backup plus slim for £30 and a few other technical bits and bobs.
Been after one for months for xbox one and they all been holding there price, works a treat.
Was reduced to clear?as sainsburys are getting rid of a lot of there electrical and gm due to argos moving in store so keep eye on your local stores.
