It was indeed one of these sketchy courier services. They dumped my package by the front door of our apartment building at 10pm on a Saturday night in NYC. Or they claim to have. An hour later when I got home it was nowhere to be seen. I waited home most of the day for it until I had to go out to a previous engagement, too. The previous time I had a next day delivery, they claimed to have attempted delivery mid-evening while I was at home but never even rang the bell.
