When I had mine (back in Dec for Hawaii), it was a drive thru location at Walgreens in Phoenix. They had trailers set up outside to process the test and the results came back online through another party. These were all independent contractors and Walgreens was just the location - did not use Walgreen's employees. Not sure if it is the same all across the country or if anything has changed since then. Worked slick as a whistle!
