> package is delivered unexpectedly

I...huh? How?

Are you a darknet dropshipper? (Nothing wrong with that, just can't imagine what carrier doesn't give you a tracking number that you can get alerts on delivery/check status of.)

Family sometimes send me packages unannounced, not all shippers (especially international) give real-time tracking numbers, not everyone in our household keeps perfect track of their inbound shipments, and sometimes delivery agents just make a mistake - one time I came home from work to a big screen TV on my porch. It was supposed to go to neighbor, but that's something I wouldn't want on my porch for a week - even if I don't care if it's stolen, it's like a big "No one is home here!" sign.

All those Chinese products with free shipping were like that. They'd show up one day randomly. Also, I buy most of my stuff online so there's always something in flight. Books, toothpaste, whatever.

I use 17track for that. It's an app that I drop all my AliExpress/Amazon/eBay tracking codes in and I will get a push notification that the package has been delivered. Don't need a camera monitoring my neighbours front door for that.

Heh, so never had a friend or family ship you something?

Not without them telling me in advance, no.

We order a lot online. I can't even count how many times we get notified of a delivery via the app, but it is nowhere. A day or three later is when it actually shows up on our door. When we've complained, we've been told to wait a day or three. Sometimes the notification comes in a day late too. So a door camera helps us know when to look out for a delivery for realzies. Oh, and if a neighbor drops by while we are out, we can chat real quick over the door camera.

I'm guessing you don't buy stuff off of AliExpress much? Sometimes the shipping window is like 1 month or bigger, you just never know when it will finally reach your house.
