I watch shark tank on Friday nights at 9:00 and this one had a man who started Doorman only in San Francisco. He charges someone starting at $3.99 a package to ship whatever you buy to his warehouse and from there you set the delivery time. He was mainly delivering at night or when it was convenient for you. As an example he had a dummy door with notes plastered on it. One of the sharks actually invested in it. More cities to follow as he grows. Deliveries were made by personal vehicles. Any comments?
