Where's that package?

A service I found through a blog I read is called www.trackmyshipments.com - this website allows you to track packages that you have sent or are expecting. I recently signed up for it and it was very easy to track a package I was expecting from Barnes and Noble. I forwarded them the e-mail with the shipping confirmation I received and set to get e-mails whenever my package information was updated. I received e-mails every step along the way, I knew where my package was at all times and I got an e-mail when it was delivered letting me know who had signed for it. It has been very helpful for me to know where stuff is and I'm hoping it will continue to be so helpful and it's free too. No more having to go to each merchant to track packages or to the shipping company's website cutting and pasting tracking numbers.
