Americans can order more free COVID-19 tests online for home delivery.
The U.S. government is offering to send another round of four at-home virus tests ahead of the typical surge in cases during the winter holiday season.
Anyone who did not order a batch of four COVID-19 tests in September can secure up to eight of them this time around starting Monday at COVIDtests.gov. The U.S. Postal Service will deliver them for free.
