The United States Postal Service is considering cutting back mail delivery from six days to five, eliminating Saturday mail.
The postmaster general says more people are paying bills and sending messages online, leading to a major drop in first class mail.
The amount of mail delivered fell from 213 billion items to 170 billion in the past four years.
Congress will have to approve the service cutbacks.
The postal service is threatening increased prices and longer delivery times if a day is not cut.
