Here's an obvious question: Why do none of the major delivery services provide universal visibility? Universal visibility goes beyond just looking at a single package, to viewing the stream of packages coming to your location. It seems a relatively straightforward step to allow me to create an account, link it with an address, and then view all packages coming to the address. On Tuesday, I just finished damning a company over a warranty repair, not knowing they had shipping it a week before and it would arrive the next day. Before Christmas, I paid $2 for a home pickup of a package -- not knowing that other packages would arrive that day.
This is the type of competitive discriminator that would cause me to pick one service over another (or a vendor who uses my preferred service). You can also envision followon capabilities like rerouting in transit (currently available for companies) or held deliveries (plenty of times I could save the UPS driver a visit or 3 by not bothering to attempt deliveries when I'm not there).
And I can't understand why UPS charges so much more than Fedex on my small business account. Its not even close -- and Fedex gives easy access to free boxes if you use Express Saver.
