It's time to start stocking up on those Forever stamps. The cost of mailing a letter is going up a penny.
The Postal Service says a first-class stamp will cost 42 cents as of May 12. The price of the Forever stamp will go up at the same time. But until then, those stamps can still be had for 41 cents and will remain good after the rate increase.
The post office says it has sold five billion Forever stamps since they were introduced last April. It's planning to have another five billion in stock to meet the expected demand before the price change.
Charges for other services are also changing. But specifics on prices for Priority and Express Mail will be announced later.
Postage rates last went up last May, when a first-class stamp jumped two cents.
