Shamelessly nabbed from MSE so thanks to claire21 over there.
This TV is priced at £799 reduced from £1149, but when you add to basket and go through to checkout it appears at £449. It looks like the £350 off certain TVs promotional discount is being applied twice.
Free 5 year warranty and 5% Quidco too which should track OK as you're not using any codes which brings it down to £426.55.
Seems like a bargain to me. Just wish I could afford it myself right now :(
