This site states this specific wording directly beneath its three pricing tiers: totals shown reflect the listed per-bottle price multiplied by bottle count.
Naming the calculation method explicitly — per-bottle price times bottle count — is worth crediting as a transparent explanation of how each total figure was reached, rather than leaving the math unexplained.
This site is direct immediately after: confirm your final total, including shipping, at checkout — worth reading both statements together as this site's complete pricing-transparency framing.
