Mailing a letter costs a little more, with the price of a first class stamp rising to .42 cents. People who planned ahead and bought Forever Stamps for .41 cents each can still use them without extra postage.

Forever Stamps also are going up to .42 cents, but buyers might want to stock up anyway, looking ahead to next May when prices are expected to be going up again.

The cost to mail a post card also went up a penny, to .27 cents, certified mail costs a nickel more, at $2.70 and priority and express mail also are getting more expensive.
