If I am not home for a U.P.S. conferral, what happen to the box?
Answers: They try the next sunshine and the day after that... And later hold it at the local UPS distribution center for you to pickup.
You can call the number on the thought left for you by UPS, and request that they hold it for pickup or deliver it to a different address.
It's also at the driver's discretion whether he leaves it on your doorstep or not.
they will try again
