2 weeks ago I managed to bag myself a 65 inch C6 from Currys with 5 year warranty, it was an in store only clearance price of £1999 which I found out about on a discount site - they only had the display model left which they sold to me for £1899. I was pushing for more, but they wouldn't budge further.
Overall though - I'm extremely chuffed with it for that price! Slightly wary with it being ex-display on vivid mode for the majority of it's life, but no issues discovered at all as of yet. Picture is fantastic in every way moving up from a 50UT50 Panasonic Plasma. 1 thing I'm not convinced on for anybody buying from Currys - they don't seem to supply any documentation detailing the 5 year warranty. Having googled, this is a common issue which I will be following up with them.
