Had my eye on a few TVs in this price range for a while and this one has won for me. Has a decent spec for the cash and with Argos reducing it to £479.00 i gambled on a voucher code which was meant for TVs over £499 and it knocked another 10% off. Not sure if i get the 3% Quidco back due to the voucher used, but you never know?
Anyway, the 10% knocked it down to £431.10 for a 43" 4K TV from a decent brand. Decent spec on it too, and has HDR which was a must for me.
Discount code i used was TV10
