For the first time since 1919, the price of a first-class stamp has dropped. It’s now 47 cents instead of 49. But to those who want refunds for the extra two cents they spent on “Forever” stamps, the U-S Postal Service has a flat answer — No. The reason the price of a postage stamp has dropped is because a special surcharge the federal government authorized in 2014 has expired. But the Postal Service wants it back, saying it continues to record unsustainable financial losses due to changing market conditions and government mandates that prevent them from responding. Officials say pricing is an important component to putting the Postal Service back on a sustainable financial path.
