My shopping in 1970 was either at the military base grocery store where items came in the strangest sizes. Milk only came in quarts but horseradish also came only in quarts ( do you know how long it takes to use a QUART of horseradish??? Cooking oil and pancake syrup only came in gallon glass jugs.
You had to get a "permit" to buys men's white t-shirts or razor blades and your toilet paper purchases had to be signed for (my husband was called in twice because I made "excessive" TP purchases......I had salmonella for a while and, believe me, excessive toilet paper was called for!).
The other shopping was done at the bazaar, where they didn't give a darn what you bought but toilet paper wasn't available.
