PackTrack Informative - Great site to track all your packages for shipping. UPS, FEDEX, USPS, and many more!
I would like to recommend this site, for all your package tracking needs:
It allows you track more then one package at a time, saves your information, so you can track through out the day, until your delivery arrives.
Best of all, you can enter tracking numbers from many different shipping companies, you are not just limited to one.
The site is very user friendly.
