One of my grandmothers was a heavy Sears shopper. The day they announced the catalog would be No More was a hard day for her... I'm not sure they got all her business--I know she shopped Wards sometimes, and Penney's. Indeed, one strong memory was when she'd come and visit us, and liked visiting the Penney's in our mall. There were so much more interesting stores, I thought at the time... My mother said, however, that Grandma wasn't happy with the store she had in her home mall.
The house I grew up in was also heavily Sears. Whoever owned it in the late 60s bought at least the water heater and one furnace there. Probably much more, too. My parents had a Kenmore washer/dryer, and the house had a portable Kenmore dishwasher left behind by some previous occupant. However, the Sears influence was all "old." My family almost never shopped there in the 80s that I can recall, except one time when there was a good sale on mattresses.
