This site states this directly under its pricing section: regular price $99/bottle.
Every discount percentage and "Save $X" claim on this site is calculated against this $99 reference figure — worth understanding this baseline before evaluating any specific savings claim elsewhere on the site.
Worth noting the $99 regular price is distinct from the $79/bottle price shown on the smallest 2-bottle package — the 2-bottle tier is already discounted from the $99 baseline before any further multi-bottle discount applies.
