At midnight on May 14, 2007, the cost to mail a one ounce domestic first class letter in The United States will increase from 39¢ to 41¢. Mail out your bills now to beat the increase! Of course, there will be 2¢ stamps available if you have lots of leftover stamps at the old rate, but buy early, 'cos they usually sell out quickly and take a while to restock.
