I read about this about a week ago. They are also making a stamp called a forever stamp or something. The stamp will cost the same as a regular stamp at the time of the increase but if stamps ever go up again that stamp will still be good. So you will pay somethign like 46 cents for the stamp but if they increase again to say 50 cents a stamp, you will still be able to use that 46 cent stamp and not pay the difference of the increase.
