Why would anyone use this, wait 2 days round trip and give Amazon their COVID-19 detection status when there are literal at-home *tests* (eg BinaxNOW) that you can buy off the shelf at a local grocery store for half the price and get results in 15-20 minutes?
Even the fact that it's PCR vs antigen isn't a motivator, if I test postive with antigen test I'm likely not going to have any issues accessing a PCR test from a local provider.
