The price of stamps will go up to 46 cents Sunday.
The U.S. Postal Service will also introduce its Global Forever Stamp which will allow customers to mail letters anywhere in the world for one set price of $1.10. USPS first announced the price change in October.
The new price is a penny increase from the previous price, according to the news release. Forever stamps are always good for mailing a one-ounce letter anytime in the future regardless of price changes.
