Delivering Something Extra - New York Times SINCE 1907, United Parcel Service has been delivering packages ordered by consumers. Next week, the company plans to deliver packages they have not ordered, in a test of an effort to expand into direct marketing. Beginning on Monday, U.P.S. will experiment in five major markets with a service it calls Direct to Door, giving advertisers and retailers a chance to provide offers and product samples to U.P.S. customers. The marketing materials will come inside small boxes labeled Direct to Door Paks, and will be delivered to customers along with merchandise they actually ordered.
