Iowans who have a home computer, a printer and access to the internet will”virtually” never again have to go to the post office. The U-S PostalService has teamed up with two private companies to launch “P-C Postage,”which is explained by Rich Watkins, a postal service spokesman for Iowa.The service enables customers to buy & print their own stamps.
