Yahoo! News - Postal Service Seeks 2-Cent Stamp Increase
"The Postal Service filed a request Friday seeking higher rates. The agency wants a 2-cent increase in first-class mail, and similar increases for other types of mail, to take effect early next year. It would increase the rate for regular mail to 39 cents from 37 cents."
I can't remember the last time I even put a stamp on something. I think this has the potential to cost me about $0.10 over its first 12 months.
