One thing I have learned.
If you use the USPO and the package doesn't arrive at the guaranteed arrival time, even 2 hours late, you can get a refund of the shipping cost if you paid it. Not sure about FedEx.
And I have found no one company to be any more reliable than another, in fact many use the same planes.
I have also found, I can go to the post office at opening and pick up my styro box, instead of having it drive around a few extra hours in the truck.
