Multiple appliance brands
There are a variety of reasons someone would choose a range of one brand, refrigerator of another, and yet others for the dishwasher, washer, freezer, etc. Aside from thinking one company might have a good oven, but not such a good dishwasher or freezer, there is a reason unrelated to the appliance itself - a social one. For example, let's say Ray and Alice live on a farm a couple miles outside the small town of Wheatridge, IA. They decide they want a new refrigerator for their kitchen. Who should they buy it from? Well, lets see, they bought their GE range a couple years ago from Don's Appliances, owned by Ray's friend Don that he knows from Farm Bureau, their Maytag laundry set a few years ago from Joe's Maytag Service, owned by Joe, a man they attend church with, and their freezer last year from R & D, the Amana dealer owned by Roger and Doris. Alice plays cards every Tuesday with Doris, and she is in their kitchen whenever Alice is hostess. Their children are also good friends. They haven't however, bought anything from Frank's Furniture since the KitchenAid dishwasher they got ten years ago. Ray has attended Rotary Club with Frank for many years, so they decide their Whirlpool refrigerator will come from Frank's, since they don't want to offend him. This may sound odd to those of you that have always lived in a big city, but is very common in rural areas where everyone knows one another. At least that was the way it was around here; my parents and many of our neighbors spread their business around for this reason. It was the exception for anyone to have appliances of all one brand name.
