£799.99 on amazon here is the amazon link
Bought lots from this company and had no problems. Not quite at this price point though. They were/are good with returns.
better buy from http://www.cramptonandmoore.co.uk/televisions/led-lcd-oled/samsung-ue65mu6220-65-inch-smart-4k-ultra-hd-hdr-curved-tv.html?source=aw&awc=6092_1532255583_5daf3ded629d009911c0f4d6cdfbf11d&utm_source=AW_Pricespy+Ltd&utm_medium=affiliate Much reliable website in 789£. Only 5£ more.
I would be more inclined to go via eBay option - they also sell through Amazon for the same price as well. This is a good price for a 65" branded TV, its a little old for me having an 8bit panel but still seems good.
