WASHINGTON – The U.S. Postal Service intends to discontinue some Saturday service beginning Aug. 1, CBS News reports.

The announcement will be made Wednesday.

“They would still be delivering Priority Mail packages, medicines, that kind of thing on Saturday, but they want to stop delivering first-class mail,” CBS News Congressional Correspondent Nancy Cordes tells WTOP.

The postal service has had Saturday delivery since 1860.

The move would save $2 billion.

Last year, the postal service lost $16 billion.
