Been looking at LG 49UH750V 49" for quite a while now and AO.com currently has £150 cash back on this TV.
Since their price match is very good and they can match most of retailers I went on pricespy to try find the same model at cheaper price. Cheapest found was at Appliances Electronics for £719.

They price matched it without any problems and also said the product will be eligible for £150 cash back.
Free next day delivery as well!
Total cost: £569
