The U.S. Postal Service is planning to eliminate next-day delivery as part of an overhaul to save $3 billion. The USPS will close nearly half of its 500 mail-processing centers next year, meaning mail will have to travel farther from the post office to a processing center. As a result, first-class mail will no longer be delivered the next day, even within a community; it will take two to three days. Delivery of periodicals will take longer, between two and nine days.
