I’m thinking about things where the brand name has become “the name” of the thing. Kleenex & Google come to mind. Here in the SE corner of the USA, we say “Coke” instead of soda or pop.

Apparently, there’s a name for this. “Generic Trademark”. https://en.wikipedia.org/wiki/Generic_trademark

Also, I really like Hershey’s. Family grew up not far from their site, was always the chocolate we had as kids. So I like your bizarro universe. :D

$500/mo. Single person, SE USA. I eat 2 meals per day and a snack. Cook all of it except for one treat meal per week.

I should add, that price might be a tad high, as my grocery bill includes things for the household like laundry detergent.
