I've had UPS packages MAILED to the Post Office and then delivered. Very strange but the Sender pays to have it shipped via UPS and then the UPS sends it via the USPS? I don't get it but prhoshay I think that is what happened to you. But then again, if the address was right per their first delivery, why didn't the USPS get it to you? I don't like having to sign for certified letters at home. I'm never there when they try to deliver them and then they take to the post office further away from where I live - because I am on the wrong side of the highway and then they are closed until I start work so I have to take off work to go sign for it. Ugh.
I use FedEx even for personal stuff. They are much more dependable here. I like UPS but see issues above with leaving at the door, I'm always afraid someone will take my package and then its just he said he dropped it off but how can I prove that?
