Mine usually shows up sometime between 12-2 (I live close to my work and usually go home for lunch, and it's normally there by the time I get home or it arrives as I'm leaving to go back). Unless I'm waiting on a package I expect to have to sign for, then it always manages to come late enough to ensure no one's home and I have to go to the post office for it.
