If you hate sending letters because it is expensive you are going to hate this information. The Postal Service announced that starting January 27th, the price of a first-class stamp will increase one cent to 46 cents. International mailings will also increase in price.
The financial crunch is largely due to a law passed in 2006 in which Congress ordered the Postal Service to put money aside for future retiree benefits.
