If you're not looking to spend too much on a major household appliance (like a dishwasher) this is the place to go! They take used appliances and repair and refurbish them for resale.
I have a dishwasher from them that looks and works like new. The best thing are the prices.
If you're looking for a specific brand or model I suggest going to a national chain but for nonspecific finds it's great.
They also accept your broken appliances.
