Forever Stamps can be bought in any desired amount and then used immediately or whenever desired later, without any required holding period, transaction and management fees, or penalty for early redemption. When Val and I go grocery shopping, the cashier often asks if we want any stamps. So long as they are selling Forever Stamps at $0.41, we shall buy a set of 20 every chance we get, at least till we have acquired close to a lifetime supply. It's like getting a dollar's worth of postage for $0.90, then $0.80, etc., depending on how high the First Class mailing eventually gets to be. The discount will keep getting steeper the longer these stamps are held before use and the more regular postage continues to climb.
There must be a catch, right? Sure enough, by law, postal rates cannot now go up more than a specified, reasonably low inflation base rate. Moreover, the ones costing just $0.41 each will probably be limited to those selling before the next rate hike, at which point the price for buying more Forever Stamps would almost certainly go up to the new one-ounce First Class postage cost, etc. (So, the early bird buyer probably gets the best long-term deal.) Then too, technology is altering the ways we do all sorts of things. Maybe, before one uses all her or his Forever Stamps, we shall all be doing everything (letters, financial transactions, and so forth) by e-mail, holographic-space-reflector-beam, or whatever. But I doubt it.
