I have to say- we have always gotten a good deal from Sears. We've bought several appliances from them and they recently replaced our furnace. The service has been excellent, both the customer service center on the phone and the installation and follow-up.
If you are really trying to save big on cost, I would definitely suggest checking out a Sears Outlet store- they sell slightly used or floor models of major appliances.
I wouldn't look there for everything, but we replaced our old dryer with one that was brand new, super efficient, etc. We got a dryer that cost almost $600 for just under $300- because there was a scratch on the front of the door!
I wouldn't do that for everything, but for something that is just sitting in the basement, I didn't really care about the scratch and I got the dryer I really wanted for less than half the regular cost.
Just shop around and compare prices and see who has the brand or style that you really want. Good Luck!
