Just got this in the ASDA Llandudno store for £188 (In store only) and not sure if it national' it might only be this store but maybe it might get reduced in other stores over the next few days so keep a look out.
I Know its not a top brand but a 50 inch UHD smart tv for £188 is great and is perfect for what i need and for those who don't have stupid money for a more well know branded name.
(They also had the Polaroid 55 inch UHD smart tv for £250)
ULTRA HD (3840 X 2160 (4K)
BUILT IN WIFI
SMART TV WITH OPEN SMART BROWSER
