The Postal Service has taken the first step toward cutting back mail delivery to five days a week.
The postal governing board agreed Wednesday to ask the independent Postal Regulatory Commission for an opinion on dropping Saturday delivery. That request goes to the commission next week.
Postal officials say the change would save more than $3 billion annually. Post offices would still remain open on Saturdays, and Express Mail would still be delivered.
Congress would have to consent to the change.
