Jan. 19 (UPI) -- The cost of mailing a 1-ounce first-class letter in the United States will return to 49 cents on Sunday, the U.S. Postal Service said.
After steady increases, the cost of a first-class stamp declined from 49 cents to 47 cents in April 2016, but will rise for the first time since 2014, returning to 49 cents.
