I went through the same thing with Fed Ex and having my bicycle engine delivered. Day one I get a notice on the door knob that they were there at 1345, nobody was home and the delivery needed a signature. I figured the next day I would work from home in the afternoon to get the engine so I go home at 1130 and there is another door knob notice that they were there at 0830 and nobody was home and they would attempt one more try. This time I signed the back of the door knob hanger and left it there so they could drop it off without me being there and the next day I get home at 1600 and the hanger was still there. They didn't get there until 1645 to drop the engine off so I met them this time. I asked the guy if they normally delivered around the same time each day based on their route and he said they normally make their stops within 2 hours in a specific area from day to day, but he gets bored driving the same route all the time so he mixes it up a lot. So now I know I should never expect a delivery from Fed Ex at any particular time of day.
