This has now happened twice in the last three weeks where some carrier has been calling me and my SO regarding package deliveries to our residence. The first time they called her and I freaked out about it because my UPS app didn't show a package being delivered and I read about possible break-ins. She went home and sure enough, it was a package delivery. I just had another call and sure enough, it was another package delivery.
When I track it looks like the carrier is indeed AMZL_US. I'm confused has Amazon started doing deliveries themselves???
