No one around here gets their mail delivered anyway. We have to pay extra for box rent and drive 5 miles to the paved road where the closed post office is and a further 14 miles to the post office. My local post office has been closed over a year out of the last 5 but I still have to pay box rent. Maybe they should charge city people for mail delivery like us rural customers so the operation would not go broke.
Every other business in business does it that way, otherwise they don't stay in business.
That box should be free if they are not delivering to your house. I have that situation, except I live 2 blocks away.
