 WDAL News, Time 754. The U.S. Postal Service is raising the price of Forever Stamps later this month. Stamps will sell for 73 cents beginning on July the 14th. That's up a nickel from the current price. Other postage costs are going up too, including postcard and metered letter rates. The increases are part of a decade-long financial outline that USPS is calling the Delivering for America Plan. I'm Mark Mayfield.
