I have been thinking about buying this TV for some time. At this price it looks like a bargain. If you can make some payment in store before 31 July you get the free Panasonic 5 Year Guarantee.
(I think Laskys are also doing the same deal but no guarantee)
As Sound & Vision have this TV in store you could ask John Lewis to price match, but I'm keen to support local business! (Bolton/Manchester)
(PS - first post - be gentle!!)
