I don't know how common this is, but the Boston area has https://www.cleenland.com/ https://www.cleenland.com/, a store that offers most household items in bulk, so you can go fill up a mason jar or something with detergent or shampoo. Maybe something like this exists in other cities? If not it should, and really it should just be an aisle in the grocery store.
