Can I use 2 forever stamps for extra postage?
Avoid placing two Forever stamps on a mail piece for heavier mail. Additional ounces are much cheaper costing only $0.24 per additional ounce rather than $0.66 for a one ounce letter. If you add two Forever stamps to a 2-ounce letter, you would be paying for an item that should only cost $0.84.
