Toshiba state the price as £849.00, so that's quite a saving.
It comes with a free case (worth £19.99), free 2GB Kingston memory stick (worth £9.99) and free backup software with one year subscription to online storage (worth £49.99).
This deal was spotted in-store at Staples in Sheffield.
It doesn't appear to be available online, but I assume it's the same price at other Staples stores.
