The used bookstore owner who knows every regular by name is running a community center that happens to sell books.

Plenty of small businesses are really gathering places with a product attached. A shop where the owner knows every regular, keeps things aside for people and remembers what you are halfway through is providing something that has no price on the shelf, and the books are what keeps the lights on. Towns lose those first and only notice afterward.

Spend your money in one of those places this month rather than online. Go often enough to be recognized, and tell the owner what you are looking for instead of searching in silence.
