now tracking your packages could not get any better. now there is a web that you could go and track all the major mailing companies (USPS, FedEx, UPS, DHL) at one place only. all you have to do is to create an account (for free) and then enter your tracking number and it will display where your package has been with a trace map using google.
in the future this company is trying to incorporate other small companies but in order to do so they need more data to collect. the website is http://ww.trackthepack.com/.
