My MIL has everything she orders online delivered to my house.
She does this because about 20 years ago, she and my FIL moved to an acreage about 10 miles outside of the town where my wife grew up. This acreage's address was in a different ZIP code for a neighboring town. My in-laws both worked in the town where my wife grew up, so they kept a PO Box there as their chief mailing address. My MIL is convinced that the fact she has a PO Box in New Podunk, IA but has a street address in South Podunk, IA will confuse any parcel services and lead to undelivered packages. While she was still working, she had all her packages delivered to her office (which is in the town where they have the PO Box).
Rather than just change their address completely to the place they've lived since 2006, she started having packages delivered to our house. My wife works in her hometown, so every day my MIL drives into town (a 20 mile round trip) to get packages out of my wife's car. One time we were out of town in the dead of winter and she ordered something that could freeze and be damaged. I had to call a buddy to stop by my house and drag it into a warm space.
All because she's convinced that if she orders packages to the place she actually lives and has actually lived for nearly 20 years they won't arrive.
