re: Which of these scams did your parents/grandparents fall for?

Yep- same. We had various Amway items, my parents even signed up for a short time to try to market Amway. We had the full set of encyclopedias and the subscription for the year book. Our set was pretty old and we complained that we needed a later version but mom said that’s why we had the yearbook- it was supposed to keep us current, lol! Someone sold them a bill of goods! Mom and her mom bought plenty Avon. Mom went to Tupperware parties and we had lots- never hosted one. I remember multiple Kirby Vacuum demonstrations but that was one thing they didn’t fall for, probably because it was so expensive.
