In the 70's, 80's, and 90's there was no "online" and one would plan to buy several miles away, if not cities away, have your "my elder father is staying with me stories ready, and start to learn what stores had interesting diapers, and not depends. There was a store 12 miles away with 3 tab Attends. Worth the trip but just as nerve wracking as trying to buy booze in a State Store at 17, or get served at a bar when under 21, or buy diaper storybooks at an adult book store. Never knew if you really needed all those practiced lines, but after awhile it felt like you could bluff any poker player with that expressionless stare at the cashier (" go on, just say something"). Getting in the car after was like winning the lottery or being kissed on a first date. Makes you wonder if as part of training, FBI agents were told to buy diapers in pharmacies. J Edgar would have (really) loved that.
Internet dos take almost all the worry out of purchase, but sometimes there is a rip in the package.
