Effective Sunday, it costs more to mail a letter. The cost of a first-class postage stamp is now 49 cents, up three cents.
Regulators approved the price hike in December. Many won't feel the increase right away as forever stamps are good for first-class postage no matter the rate.
The last increase for stamps was a year ago when the cost of sending a letter rose by a penny to 46 cents.
The U.S. Postal Service lost $5 billion last year and has been trying to get Congress to let it end Saturday delivery and reduce payments on retiree health benefits.
