WASHINGTON -- Not just diamonds are forever. Add stamps to the list. The post office is planning a ''forever" stamp for letters, good no matter how many times postal rates increase.
That means people could say goodbye to those annoying 2- or 3-cent stamps that have to be added to letters every time rates go up.
The idea for the special stamps, which would be sold at the same price as other first-class stamps, was included in proposals announced yesterday that would also raise stamp prices 3 cents -- to 42 cents -- next year.
