It appears Saturday delivery of first-class mail will continue for a bit longer.

The United States Postal Service in February announced plans to end six-day-a-week delivery of letters.

But Congress responded by passing a measure requiring the continuation of Saturday service.

The Postal Service continues to lose billions of dollars a year and the end of Saturday letter delivery was one step designed to address the problem.

Postal Service officials had estimated switching to a five-day-a-week delivery schedule could save about $2 billion annually.
