how much is a usa stamp cost
USPS raises price of stamps. The U.S. Postal service is now charging Americans a penny more for stamps and postcard mailings. The price of a first-class stamp for domestic mail rose Sunday from 45 cents to 46 cents, while postcards cost 33 cents to send. The USPS rolled out the pricing changes alongside a new stamp â the Global Forever â which lets people mail one-ounce letters to anywhere in the world for $1.10. Other new services include free tracking for packages and the option of receiving a signature upon delivery for critical mail items, WALA reports.
