When I get stuff shipped to me, I like to track it online. Since the only stuff ever shipped to me is stuff I really want, I tend to leave the tracking page up and reload compulsively about every 4 minutes.
SimpleTracking.com is a service that offers your tracking list in an rss feed. When a new stop is listed, it ads it to the rss feed, and your reader should alert you.
It’s not dodgy at all, they use the released API’s from the shipping services themselves. Quite cool in my opinion.
