Budget tip.... this does not help in an emergency but if you can see your gonna need one and have a few months to look this can work.
In our Lowes and Sears, they always put miss orders, dented and so on in the back at sometimes 1/2 off. I have bought a stove and a microwave this way. I also need to start looking for a dishwasher. My stove was dented real bad on the side which is hidden because my stove sits between 2 cabinets. In most cases these are special order items so on higher end and they come with waranty.
Note that our Sears does have a seperate building for this and they do offer scratch/dent and refurbished. Also I am told by a builder that in larger areas they have a Scratch/Dent warehouse that business sell to, ask the manager in your local store where they send these appliances. Remember they get new items weekly so check often.
