If you delight each Saturday in grabbing your magazine or movie from the mailbox, or just in seeing whatever the mail person brings — enjoy it while it lasts.

The financially struggling U.S. Postal Service said Wednesday it will stop delivering mail on Saturdays but continue to distribute packages six days a week, in an apparent end-run around an unaccommodating Congress.

The service expects the Saturday mail cutback to begin the week of Aug. 5 and to save about $2 billion annually, d Postmaster General and CEO Patrick R. Donahoe said.

“Our financial condition is urgent,” Donahoe said at a news conference in Washington, D.C.

The move accentuates one of the agency’s strong points — package delivery has increased by 14 percent since 2010, postal officials say, while the delivery of letters and other mail has declined with the increasing use of email and texting.

Yet for folks like Jeff Bray of Pembroke Pines, who looks forward to opening his mailbox each day, and feels most comfortable getting his bills in the mail and paying them with paper checks, the loss of Saturday delivery is a hard pill to swallow.

“We remember when we could get mail delivered twice a day, and now they are taking away our Saturdays,” said Bray, 65, a public relations executive in Hollywood. “It’s just a sad state of affairs.”

Under the new plan, mail would be delivered to homes and businesses Monday through Friday, but would still be delivered to post office boxes on Saturdays. Post offices now open on Saturdays would remain open on Saturdays.

Arnold Slotkin, a certified public accountant whose office is in Miami Beach, is worried the cutback will hurt his business.

“I would have no objection to it being Wednesday,” said Slotkin, 84, who lives in Hollywood. “Chop it out of the middle of the week, and that way there would be a day delay. But two days in a row is really disruptive.”

In Florida, 10,000 employees work at 188 post offices and processing plants from Fort Pierce to Key West, said South Florida spokeswoman Debbie Fetterly. No layoffs are planned at this time, she said.

Over the past several years, the Postal Service has advocated shifting to a five-day delivery schedule for mail and packages — and it repeatedly but unsuccessfully appealed to Congress to approve the move. Though an independent agency, the service gets no tax dollars for its day-to-day operations but is subject to congressional control.

Congress has included a ban on five-day delivery in its appropriations bill. But because the federal government is now operating under a temporary spending measure, rather than an appropriations bill, Donahoe says it’s the agency’s interpretation that it can make the change itself.

“This is not like a ‘gotcha’ or anything like that,” he said. The agency is essentially asking Congress not to reimpose the ban when the spending measure expires on March 27 and he said he would work with Congress on the issue.

The agency clearly thinks it has a majority of the American public on its side regarding the change.

Postal Service market research and other research indicated that nearly 7 in 10 Americans support the switch to five-day delivery as a way to reduce costs, the agency said.

“The Postal Service is advancing an important new approach to delivery that reflects the strong growth of our package business and responds to the financial realities resulting from America’s changing mailing habits,” Donahoe said. “We developed this approach by working with our customers to understand their delivery needs and by identifying creative ways to generate significant cost savings.”
