How the Decline of the Post Office Affects You - The Street Officials at the financially troubled U.S. Postal Service said Thursday that they may close more than 250 mail-processing facilities across the country and reduce service standards for first-class mail to cut costs. Consumers shouldn't expect to see major changes within the shipping industry. The Postal Service had more facilities than it needed at the height of its business. Without any closures, the post office can handle 300 billion pieces of mail, but is getting only about 176 billion. Susan Rosenberg, spokeswoman for UPS, confirms the company had no plans to change its business model or pricing scheme in light of the Postal Service's latest financial woes.
