This is my first post so apologies if it is not correct. Our washing machine has died and my wife wanted me to find a 9kg machine with a 5 year warranty asap and I came across this deal from Tesco which seems pretty good. Was £459 but £367.20 with Ecoupon code TDX-HJKT (20% off - expires 20/11/16). 2 year warranty comes as standard. You will have to redeem the extra 3 years online within 90 days of purchase by completing an online registration form - http://www.samsung.com/uk/fiveyearwarranty/onlineregistration.html.
Hope this helps someone else.
