Just a quick reminder that postage is going up by a penny for first-class mail on January 27, 2013. So instead of paying $0.45 per piece of mail, you’ll pay $0.46.
Now’s a great time to invest in Forever Stamps as they currently only cost $0.45 (until January 27, 2013), but they allow you to mail letters to anywhere in the U.S. indefinitely, no matter how much the price of a stamp increases.

Tip: you can often get Forever Stamps for a few cents less per stamp by purchasing them on eBay.
