Mailing a letter will now cost you a penny more, as U.S. Postal Service rate changes went into effect Sunday.
Stamp prices increased one cent, from 45 cents to 46 cents, to
mail one-ounce letters, effective Jan. 27. The cost for letters weighing
more than one ounce remain the same - 20 cents for each additional
Postcard stamps also saw a one-cent increase, from 32 cents to
33 cents. Letters under one ounce mailed anywhere internationally now
Those looking to save a bit could stock up on Forever stamps (which cost 45 cents until the one-cent increase on Jan. 27). These are usable even after stamp prices increase.
