The US Postal Service did not deliver a package (USPS Employees Please?)?

if there was not a metered postage on the parcel, they would refuse to deliver on the other end due to security percautions, packages that are sent with postage stamps instead of meter prints are usually returned. if it WAS metered, and still not delivered, it may have been the letter carrier felt the package could not be left in a safe place, was the mail box too small , was the driveway gated? was a barking dog present? if it was in a rural area, and made it past the post office, only the carrier would know why it was not left..many carriers will take the time to place a package at the door or beside the garage, while some carriers will not leave a parcel just laying there. "just leave the box" is not always possible, you can;t just toss it out on the side of the road, near the house...and if the carrier was unable to access the property safely, then he/she had no choice but to return it to the post office and it sat there waiting on another attempt. This is why I send ALL my packages UPS...much more reliable than any government run agency. Go with the BROWN TRUX!
