Can I Invest in the Post Office? Postal Rates Going Up Again

In case you haven't heard, and there hasn't been much news on this that I've seen, postage rates are going up Monday, May 14. First class rates for the first ounce are increasing by 2 cents, to 41 cents. Postcard postage is going from 24 cents to 26 cents. Priority mail is going from $4.05 to $4.60. Some of the new rates can be found at the USPS web site.
