Bestbuy have knocked £50 off the price of the LG 50PK350 50" plasma TV, to bring the price down to match that at Richer Sounds. The difference is, best buy offer 10% quidco, potentially making this tv £494.99 - An absolute steal for a 50" full HD plasma!
Worth noting - this is their bottom line plasma TV - so it only has 1 HDMI port at the back, and one at the bottom. As a result, its probably best for those who are using a AV reciever to switch HDMIs. Reviews are pretty good, but it doesn't have an anti-reflective coating on the screen, so if you're going to have your TV near a window, this might not be for you. It also doesn't have freeview HD or freesat, so you need your own HD source (ie sky or Virgin).
