[Personal] "Delivered"?

The past week I have been constantly tracking a package via USPS website. I had the package sent to my work address as someone would be there to sign for it during office hours. This morning I was pretty happy to see the status changed to "Delivered", so when I didn't get the package this afternoon, I enquired about it at the company mail room. Turns out USPS' definition of "Delivered" is special - it means the package has been delivered to the local office, not the final destination. I guess I will have to wait one more day to put my hands on my 6315 case.
