Maybe more advice than a deal
As you know the price went back up to £649 on amazon but its available at dixons for £575. However you dont get £100 cash back from dixons.
So if you have ultimate rewards or royalites gold etc.. but it from amazon for £649 claim the £70 back from your bank for spotting it cheaper elsewhere and you are still eligible to get the £100 cashback from toshiba as you bought from amazon
Not sure the above qualifies for a deal but it worked for me and hopefully will help some people outhttp://www.amazon.co.uk/Toshiba-42XV635DB-42-inch-Widescreen-Freeview/dp/B00221AZRS
