(NEXSTAR) – Before holiday shopping mania fully sets in, most mail carriers are taking a break this week. The United States Postal Service will not be operating Thursday as the agency observes Thanksgiving, a federal holiday. USPS carriers will not be on their routes, and caller service and P.O. Box service will also not be available. The only service that will be available from USPS is Priority Mail Express, which is still delivered on Sundays and holidays. All USPS services will return back to normal on Black Friday, which is not an official holiday. Thanksgiving 2024: What recipes are Louisiana cooks looking for?
