Track multiple packages with maps using TrackThePack
Package tracking is really one of the better inventions of the 20th century. One of my favorite tools for said activitiy is TrackThePack, a delightfully simple tool that lets you track packages from a multitude of services, and keep them together in one simple list. It also throws each shipping location the package visits onto a map, which is neat, but mostly useless.
If you're unregistered, you can only run a single tracking number at a time. Registered users get the added benefit of pulling in the package updates as an RSS or iCal notification feed. People who will be away from a computer can also sign up to get SMS updates, a handy feature offered by some (but not all) package carriers. This way you can get it from all of them without sharing any of your personal information.
For heavy-duty users, the service offers a Firefox extension that lets you track a package just by right-clicking on the tracking number, which will automatically add it to your package queue.

trackmyshipments.com offers the ability for you to forward tracking e-mails and it automatically adds the tracking info for you. If you're someone who ships 5+ packages a day, you have no interested in manually adding tracking info.
Think about it: if you're someone who tracks few enough packages that it's easy for you to manually add them, then you're probably going to just use the UPS/FedEx interface. Anyone who really tracks a lot of packages needs more automated functionality.
On the upside, it's much better looking that the alternative I mentioned above. I'll move over immediately once they start include automatic tracking from e-mails I forward.
I personally like the other provider better, www.packagetrackr.com, I discovered this site from facebook, it provides a widget to allow you share tracking info with friends (kinda show off, right?), and with google maps. Also I found a vista sidebar gadget from www.packagetrackr.com, which helps a lot when you do multiple tracking or monitoring the delivery status.
About the trackmyshipments.com, I think they pay the upstair person to post msg like that. It requires register & pay $20 per year...At least, not working for me.
