Don't worry, GSA is funding my entire trip - gas, hotels and per diem.
Fedex definitely gets theirs from us. I ship about 100 lbs a week. You should see what our supply office ships. It is ridiculous. We get tons of stuff delivered to our HQ office in Salt Lake only to repack it and ship it out to the satellite offices. I got a bunch of blank stares when I asked "why don't we just have it shipped directly to the substations in the first place."
