A local press publisher in Croatia (Tisak) did just that: leveraged their distribution network for overnight package delivery. The system works better for packages than post, since you send and pick up the parcel at their newsstands (there's always one nearby) at your leisure, avoiding the annoying "delivery failed, pick up at the post office" notices you'd get from the postman attempting delivery while you are at work. It was also helped by the fact that the national postal service here is notoriously slow and not exactly reliable.
