   Usage: Store, Shop. The English call the place where
          goods are sold (however large or splendid it may be) a
          shop, and confine the word store to its original
          meaning; viz., a warehouse, or place where goods are
          stored. In America the word store is applied to all
          places, except the smallest, where goods are sold. In
          some British colonies the word store is used as in the
          United States.

                A beggarly account of empty boxes. --Shak.
