Taking a cue from a growing trend in the private sector, the United States Postal Service wants to begin testing a same-day delivery program in one lucky metropolitan area. Dubbed the "Metro Post," the service would deliver items ordered from certain e-commerce partners before 3 PM to households between 4 and 8 PM that evening.

The USPS hasn't yet named what city it wants to test the program in, or how much delivery will cost. It's currently looking for ecommerce companies with 7 to 10 physical locations (at least one of which in the given test city) that it can partner with.

Last week, Wal-Mart announced that it had begun testing its own same-day delivery service in four metropolitan areas. That service costs $10 and is made possible by the USPS's bitter rival, UPS.
