Not all that usefull in urban areas, but in the sticks ...
Trialling this in an urban or suburban area is a mistake.
Too many neighbours to bother and it would only be used by people too lazy or time poor to go to the local chemist or corner store.
Providing deliveries to people in remote areas would avoid the noise complaints. Only the target of the delivery is likely to hear the drone and it would be serving a definite need for remote families.
Might be better to use a hybrid fixed wing - vtol drone configuration that can handle significant distance and weight while maintaining landing accuracy.
