i dont have a specific deal for you but i highly reccomend buying new units.
i went the used/refurbished route, ended up buying a replacement washer 2-3 months later.
within 6 months the dryer needed a $50 valve replaced that i changed myself. it was exceptionally loud for a year or so and finally gave out completely.
i also reccomend whirlpool/kenmore over other brands. they make good appliances.
I'm not sure if it's a sale or regular price. I do know that they will usually beat any quote you bring them for the same items by 10%. Also they are pretty receptive to haggling.
This isnt a deal, but my wife and I were out and about last night and decided to check out some home appliances. We definatley love the Electrolux washer and dryer. They are absolutely badass.
