Price is even lower with S&S.
Price comes out to ~$6.09 per test. Looking at my email this pack was this price around Prime Day from last October as well, but it’s cheaper than the usual $18 price.
You can attempt to get these reimbursed with your insurance, but some find it’s not worth the effort.
