"A dead drop or dead letter box is a method of espionage tradecraft used to pass items between two individuals using a secret location and thus does not require them to meet directly. Using a dead drop permits a case officer and agent to exchange objects and information while maintaining operational security. The method stands in contrast to the live drop, so called because two persons meet to exchange items or information." Wikipedia
Why nobody uses dead drop delivery? Given current situation with controlled deliveries it should be much safer for both parties. It makes truly automatic vending possible. Eliminates need in communication. It's faster than mail delivery.
