Announced last December as part of a larger Biden administration initiative to combat surging Omicron cases, over 500 million test kits — later upped to 1 billion — have been made available to all Americans. The Biden administration on Tuesday launched a new website, COVIDtests.gov, where people can order COVID-19 tests for free. The website will take you to the U.S. Postal Service website, where you enter your name and address for shipping. No billing information is required because the tests are free.
