Yes, groceries were purchased with the simple promise to pay for them later. There were no such things as credit cards in those days. There was no interest or surcharge, just a “gentleman’s agreement” to settle accounts when we could. Yes, I’m sure, everything was in a ledger somewhere. Groceries could also be delivered. Sometimes Mom would call and order them. But, even if she shopped in the store, she would have them delivered. Remember, we didn’t have a car and walking all the way up and down hills juggling paper sacks just wouldn’t have worked. An “errand boy” would arrive, sometime that day, on a bicycle or by car.
