House of Fraser have the G20 at £679.99 at the moment but use the voucher code FRIENDS10 (thanks lucerysmum) and this takes 10% off.
Not as good as the John Lewis deal of £599 but this also includes the 5 year guarantee for anybody that missed that deal.
Quidco may also be available bringing price down further.
Panasonic The G20 Series includes a DVB-S tuner for Free sat HD and a DVB-T2 tuner for Free view HD providing you with a convenient, subscription free way of watching HD contents like sport, as well as your favourite soaps, dramas and documentaries in full HD glory wherever you are in the UK.
600Hz Sub field Drive technology lets you view superb full-HD motion and still images with 1,080 lines of resolution. For even greater clarity with motion images, Panasonic uses its own unique image-analysis technology. This technology converts the motion in each scene into data. And each frame is practically displayed for a shorter length of time than in previous systems, to reduce after-effects.
A contrast ratio of 5,000,000:1 enables VIERA to display extremely robust blacks. New filters, improvements to the cell discharge area, and enhanced cell performance have greatly increased luminous efficiency to produce crisp blacks. And minimising the electrical pre-discharge helps to both raise contrast and save energy.
