What I did recently was make a list of all the stuff I needed, oven, hotplates, dishwasher, extractor fan, bathroom fan etc and fax the quote to Harveys, the good guys, and any other big chains, saying I wanted to purchase them all right now. Then they came back to me with prices. Then I played them all off against themselves.
It was great, only took 2 hours total and I ended up with an ex display Miele dishwasher for peanuts, great prices and free delivery. Might work out better to do it that way than search for dented products that are often only limited in numbers?
Just a suggestion that may be of help, and good luck with it all!
