The cost of mailing a letter or postcard is going up for US residents.
Beginning Sunday, the price of a first-class postal stamp will go up a penny to 45 cents. It's the first increase in more than two years.
Postage for postcards will increase by three cents to 32 cents, and letters to Canada or Mexico will go up by five cents to 85 cents.
Forever stamps will remain valid and still equal in value to the current first-class mail one-ounce rate.
