They shipped UPS, and I wasn't home when they delivered, so they left a note on my door. I called them up with the information on the note and had it delivered to my office.
I could have also drove down to UPS and picked it up there (which they are open saturday). USPS will deliver saturday, and it's usually really convenient to pick up if necessary.
I'm sure you can make similar arrangements with FedEx as well, but I have never had anything delivered by them which they couldn't leave on the porch.
