The price of a US postage stamp went up today from 39¢ to 41¢. You can now buy a "forever stamp" that will always have the value of the one-ounce letter rate, but that's not the only change being imposed by the US Postal Service. Rates will now depend on the shapes of packages and letters as well as their weight, and that could mean big changes in what you get in the mail. With the USPS more automated than ever, it's rewarding those who use packaging the new machines can handle and penalizing those who don't, as we hear from Kate Muth, Vice President of the Association for Postal Commerce.
