The U.S. Postal Service is facing a whole host of problems: The rise of electronic communications, a corresponding decline in lucrative mass-market "junk" mail, federal regulators who won't allow it to cut Saturday services or raise stamp prices, and Congressional opposition to making other cuts. While the independent agency confronts federal oversight, it's also planning to close thousands of locations, mostly in rural and sparsely populated suburban areas. (Watch a local report about closing Post Offices.) Here's a look at USPS cost-cutting, by the numbers:
