The price of postage will go up from 41 to 42 cents on May 12, but you can stave off the penny increase for a little longer if you buy Forever Stamps.

Foxbusiness.com:

"The Postal Service developed the Forever Stamp for consumers to ease the transition during price changes," said Postmaster General John Potter. "We encourage Americans to buy Forever Stamps now for 41 cents, because like the name suggests, they are good forever."

When will we see $1 or more to snail mail something? I did a little poking around and learned that the price of a stamp has doubled over the last 27 years (20 cents on November 1, 1981) and quadrupled over the last 33 years (10 cents on September 14, 1975). How much did postage cost some 50 years ago? On August 1, 1958 it cost 4 cents to mail a letter.
