Just ordered ours and it took seconds (thanks autofill!). Got the USPS confirmation email just as quickly.

People can request four free tests per household through covidtests.gov.  Officials say the tests are able to detect the latest variants and are intended to be used through the end of the year.

Earlier tests are expired, but dates have been extended on some so check the FDA site to see if you have any that are still good.

Packages of COVID-19 tests will ship starting the week of September 30. Once the package ships, you’ll receive a tracking number and updates on the expected delivery date if you entered an email address (not required).
