This might be a big help for us to track packages. I have not tried it as I haven't mailed out of the states and I use Priority Mail tracking.
This is for a free sticker for TrackThePack.com:
Which, come to think of it, is a phenomenally handy free website.
TrackThePack is a free way for people to not only keep a handy list of the various
package tracking numbers they may have, but also is a super user-friendly way to
actually track all of the packages (incoming, outgoing, whatever) in one place!
TrackThePack ties in directly with almost all the shipping services and displays
the tracking status with a map and, when available, an ETA.
They currently provide tracking for: UPS, FedEx, DHL, USPS, FedEx Smartpost,
DHL Global Mail, Canada Post and OnTrac.
