Next to the $158 total sits a crossed-out $198.
What the numbers are
$198 is two bottles at $99 each. The page itself calls struck prices the seller's comparison figure, not a total anyone recently paid. So the real price is $158, or $79 per bottle.
How to use it
Ignore the discount framing and compare the real totals across packs. At $158 you pay about $2.63 a day over 60 days. Check the final total at checkout, since the page tells you to confirm pricing there.
