I think this is already happening to the eBay tracking system:    The U.S. Postal Service (USPS) may slow down delivery times to some customers as it seeks to shave billions from its annual operations expenditure. USPS said in a statement issued on August 22 that it is holding a pre-filing conference to discuss "plans to improve mail processing and transportation" across the country. While some customers will see improved delivery times?specifically those that live within 50 miles of its largest processing facilities, others who live more rurally won't be so lucky.
