Heads up!
The price for mailing postcards within the United States goes up June 1, 2015. The new price will be 35 cents, an increase of a penny. I know the USPS said they would keep prices the same for three years but they promised never to close a certain post office or fire a longtime postmaster who gave their heart and soul either. The good news is that a new set of stamps featuring stylized birds will be Postcard Forever, thus buy at current postcard rate use, in theory, Forever.
