Well, in my area it could be someone hit by the downturn in the energy industry. Or someone gifted a car, or driving their parents' car.
However, it just as likely could be a neighbor delivering a package to its correct destination because Amazon's delivery systems cannot seem to get anything where it needs to go in the last couple of months. Of four packages lately, one ended up with my upstairs neighbor, one ended up with my across the hall neighbor, one was dropped off at the condo complex office (without any notification as to where it was...it took a week to find), and one was correctly delivered the first time. I am currently waiting on a birthday gift which failed to deliver "because the business was closed." It's a condo complex (and I put the gate code in the delivery info). We are never closed!
