Tracking information from UPS is a joke! Totally useless.
The cost of shipping by UPS [and, to be fair, by also Fedex and DHL] is unbelievable. It is a racket. I could be wrong but I believe all these companies are charging users from Puerto Rico, both senders and receivers, as international in lieu of domestic. They are bilking the Puertorican consumer. You know the ruling: "Puerto Rico belongs to, but is not a part of, the U.S." Very convenient for U.S. corporations!
And the USPS is just no viable alternative for parcels, although much more economical. What a pity!
