This site labels its two larger packages differently — "Most Popular" on 3 bottles, "Best Value" on 6 bottles — worth understanding what differentiates the two.
"Best Value" is a price-based claim, tied directly to the 6-bottle package's lowest per-bottle cost; "Most Popular" is a different kind of claim, about purchasing frequency rather than price.
This label appears directly on the pricing card without a linked, independently verifiable purchasing-data source in the materials reviewed — worth reading it as brand-stated context rather than an audited statistic.
