Out for Delivery

The limitations of internet commerce and parcel tracking become apparent when the package is listed as "out for delivery". There's still no indication of when the delivery will be made. Is it worth staying home an extra couple of hours in the morning to pick it up before heading out to work? Or going to work but sneaking home early to collect it? Actually, neither seems particularly useful since, in my previous experience, the van usually shows up about 2.30, which is roughly the middle of the day for me. Anyway, it's raining this morning, so I think I'll just wait in until the rain stops (sometime tonight, probably), or the truck comes down. How long until they augment the package tracking systems with GPS on the trucks?
