Track a Shipment:
While USPS does offer "tracking" it tells the end user next to nothing. It
shows only the time your package was mailed (which you already know form
your shippment confirmation e-mail) and the time that arrives, which you
can easily tell by looking inside your mailbox instead of using a tracking
number. There is no information about progress along the way. We feel that
this lack of detailed information is more a frustration than a service to
our customers, and so do not use USPS tracking.
