I worked (briefly) at a dollar store in the 90’s …also, years before that, sold at a flea market, where one of my long tables had a sign that said everything on it was a dollar….
Believe me, people, all sorts of people, ask that question…. a l l … d a y … l o n g.
When it was my own stuff, rather than me representing a company….
I liked to answer “$2.50”
Inevitably, the questioner would say “Then why does the sign say $1?”To which I would answer “Beats me.”
