Saw the shoppingexpress deal so I look around and find this price from ARC computers (Sydney). If you pick up in-store (they have a few around)and claim the cash back then you will be in-front. If you have to pay for the shipping (provide they ship in time) then you should at least break even and end up with a free copy of Norton 360.
