Morning Mike, I think you may have missed the boat at £625, with retailers expecting the imminent launch of the 2023 A3 OLED. However its looking unlikely the A3 will only launch in some markets including the UK or US but is expected to launch in mainland Europe according to several reliable sources,, TR, T3, AV forums etc.
This explains the sudden jump in price at some at some of the bigger retailers to £799. The A series had no direct competitor outside of LG, with LG’s rivals pumping to compete with its C series and above. With £669 Amazon or £679 being the cheapest unless any codes become available.
