My friend sends me things via USPS, and emails me the tracking number. Not sure how, or why I did it, but one day, instead of putting USPS in the address line of the new window, and going their route to put in the tracking number, I put the tracking number (copied and pasted) on the address line of the new window and it took me straight to the info for that package. Not only saved time, but did not have to type in that long number and possibly make a mistake and have to start over, or go back and forth from site to email to copy/paste. Comes in handy when there are many packages, like Christmas, birthdays, or shopping binges.
