Abstract: A cup caddy for vertically stacking and transporting cup holders and cup refills therefor in a predetermined side by side arrangement is shown. In accordance with the invention, the cup holders are uniformly alignable upon a vertical post having diametrically opposite longitudinal keyways which coact with at least one key internally disposed within a through-opening in each of the cup holders. The cup caddy includes a receptacle having a longitudinal vertical slot for containing the refills therein and providing an access thereto for the cup holders. The receptacle and post are mounted on a base in a side by side relationship and are adapted to receive a cover thereover.
