Where to buy large appliances (dishwasher)?

We got all our appliances from AO over the years. They will hound you trying to upsell some insurance, but eventually give up. We've had good experience with their delivery, removal, and their prices have always been best when we shopped around. We actually try not to buy from them because of the aggressive phone tactics, but we usually end up with them anyway as they are the best deal, and we were happy with the service provided. I'm not certain what service Amazon would provide. I would assume you would get delivery, as in dumping the pallet on your drive, as opposed to a white goods store which would allot staff to bring it into your home, dispose of the packing, dispose of the old unit, and possibly install. I personally feel like this is an important factor in these types of purchases because I cannot fit an appliance in my car to take to the tip, let alone the card and everything else they'll come with. I, too, am guilty of using Curry's as a showroom. They tend to be more expensive, so we never bought anything from them. Friends were happy with John Lewis' customer service, but again they run expensive, so I don't have any first-hand experience with them.
