IKEA kitchen sale in Edinburgh and Glasgow from 18/12/14 to 03/02/15.
4 for 3 on appliances and 50% off installation.
Not sure if this will be similar in other parts of the UK as I've seen some sales posted that start on the 18th also.
Also 0% finance on kitchens for:
12 months if you spend £1500
24 months if you spend £3000
IKEA members only but is free to join and takes about a minute to do.
