Discussion Topic (Sakai-> Forums)

  • Should you stock up on “forever” stamps? In 2007 the U.S. Postal Service began selling such stamps, which will suffice for first-class postage at any time in the future, even when rates rise. Until rates rise, these stamps cost $0.41. Would it be a good investment to buy a “lifetime supply” of them? To render your judgment, compare the historic increases postal rates (see with the CPI (p. 816). For example, you could convert postal rates at each of the dates of change to the cost in today's dollars, then see if there appears to be a recent trend that you can project into the future.
