Check pharmacies; most have been replaced by chains, but some independent pharmacies are still around, and will have a number of home staples.

Ethnic markets in general are a good option for finding locally-owned shops, but they’re going to differ in terms of what staples they actually carry.

To add to this, the “default” for a three-character ensemble in circa 90s kids media was: one (white) boy, one (white) girl, one (non-white) boy, for a 1:2 gender/race and 2:1 “diversity” ratio, which made the media feel diverse (back then this was generally considered a good thing) while still making male and white the default. In other words, a win-win that still was a setback to true diversity. Examples: Wishbone TV show and Harry Potter (if you count ginger as non-white).
