i remember the grinder. they did a good job marketing that because im sure other supermarkets must have had them too but i cant specifically recall. we werent a&p shoppers though there was one in my town. my parents really did drink the swill instant. my mom drank mostly diet soda for her caffeine though maybe avoided it for the most part entirely and my father either got some diner coffee on the way to work or drank it at the office if at all. they werent heavy consumers. 

i drank bustelo briefly at some point before buying beans from the roaster in providence in the early 90s. new york was a big step down for years until it got its coffee game together. i guess puerto rico was always an option.
