DJI drones can fly over 3 miles away. There are lots of caveats, depending on the radio conditions, battery, wind, line of sight and a few other factors. But as a single number around 3-4 miles (and back) is about as far as they'd go with the conditions.
But the regulations may be a moot point unless delivery drones can actually get where they're going and back. Commercially available quadcopter drones such as the popular DJI Phantom 2 can fly only half an hour or so on a day that isn't too windy while carrying less than a pound of payload.
