Time to stock up on those Forever stamps? From CNNMoney:
Starting January 27, the price of a first-class stamp will increase one cent to 46 cents, the Postal Service announced Thursday. Postcard postage will rise one cent as well, to 33 cents.
However, there is concern that the USPS is gaming the system by increasing rates on other classes of mail more than on forever stamps. In this way the forever feature becomes less useful. me1004 has a good review of this issue in this forum thread
