What do you guys think about USPS Forever Stamps? Some Facts: The Forever Stamp first went on sale in April 2007. Since then, more than 6 billion Forever Stamps have been sold. As the name suggests, Forever Stamps can be used to mail a one-ounce letter regardless of when the stamps are purchased or used and no matter how prices may change in the future. Forever Stamps are always sold at the same price as a regular First-Class Mail stamp. Forever Stamps are currently being sold for 41 cents and will be sold for 42 cents starting May 12, 2008. The Postal Service developed the Forever Stamp for consumers to ease the transition during price changes. There is only one Forever Stamp â it features an image of the Liberty Bell. The value of the Forever Stamp is the domestic First-Class Mail letter price in effect on the day of use. Or invest in a nice low end forever stamp counterfeiting operation...
