I know this model has been covered many times before so I wont go into the ins and outs of the model.
After much research and even more calls to John Lewis I managed to get them to price match Richer Sounds price of 679.95£.
Then I got them to apply the trade in offer by Sony for 100£. They were been adamant that they would charge me 9.95£ delivery but they take my old TV as well so suppose it saves me the agro to kart it to the store.
So for 589.85£ you get TV, 5Yrs Warranty and Delivery. Not the best deal this TV has been at but still not bad.
You get the KDL40W5710 which is the same spec as the KDL40W5500 but different colour speaker thats all.
I got this deal from the Solihull Store.
