What are forever stamps??
They are stamps that you buy at the current postage rate and can use no matter how much the rate goes up. They don't have a number marked on them. If you buy them now, you would pay the current postage rate for each, or 41 cents. When postage goes up to 42 cents, you can still put a forever stamp on a letter you want to send and it will be fine. If you want to buy them then though, you would pay 42 cents. I hope I managed to explain this somewhat clearly!What's forever stamps?
