Just got back from Ikea in Thurrock and they had a few pallets of various built-in appliances for really cheap prices. They were marked as clearance so I don't know if it's store specific or not but the deals I can remember were:
Built-in white single electric oven £29 instead of about £120(ish)
Built-in Dishwashers started at about £97
Built in Freezers were also there - think everything was AT LEAST half price.
Unfortunately I didn't have a camera phone handy so couldn't take a picture but I'm sure if you phone the store they will be able to give more information - I was tempted to buy one of everything but have only recently put a new kitchen in, sods law!
