A vintage ad from NRR’s left sidebar caught my eye:

From the ad copy, we learn that, in 1956, buying a week’s worth of food at one time and storing it at home was a new trend. It was clearly seen as a convenience to have all the food at hand. In the 50s, the big benefit was reducing the time spent making trips to the grocer. Today we might include saving the energy and pollution those trips generate, too.
This work-saving (and planet-saving) appliance, available in decorator colors, was priced at $229.95. In today’s dollars, that’s $1,852.89.
