Door-to-door sales on campus prohibited without permission Recently, University Police have received reports of magazine sales on campus. Door-to-door sales are prohibited on campus unless the seller has a transient merchants license from the state and the city, and has permission from University administration to sell door-to-door on campus. Should you be approached by such a salesperson on campus, please ask them to provide their licenses and letter from the University as proof that they are allowed to be on campus selling.
