I strongly prefer the postal service deliver my parcels. I live inside a locked building without an attendant, so to receive packages the delivery person has to come inside. But only USPS has a key to the front door. This means that when I have a UPS or FedEx delivery due, I have to stay at home all day. If I'm not, either they leave it and it gets stolen, or they leave a note and I have to stay home the next day.
