here they give on knock on the back door or one ring of bell on the front door. then they just leave the package. watch guy deliver to my next door neighbor yesterday. he threw package on porch. hit the door once with his clipboard and left. but then the postman does the same thing with something to big for box. guess you are supposed to just wander out and find them.
I have problems with this. They are too lazy to deliver so they leave a notice of delivery in the mail box. I always call the post office and tell them that IF I WANTED TO COME DOWN THERE TO PICK MY PACKAGE UP, I WOULDN'T PAY FOR MY PACKAGE TO BE DELIVERED!!! Ok, I am done. Feel better.
