Amazon, in certain areas, has the Amazon locker. It's a locker inside of a Seven Eleven or some other store and people can use these lockers to receive things. I agree that package thefts are on the rise, however, the consumer must do their homework. They have to know whether or not the package will ship in its own packaging (giving away the contents of the box) or will it come inside another box (Amazon tells you right on the item page if it's going to ship in its own box). Some items are just too big for any kind of special box or over-wrapping.
I know this world has changed drastically in the last 15 years, but man, would it be so hard to have a trusting neighbor sign for your things? Sure, not every neighbor is going to fit, but life has changed so much that a lot of us don't know our neighbors anymore (apartments and such, it's understandable).
