This site labels its 3-bottle package specifically as "Good Value," a distinct label from the "Most Popular" tag on the 6-bottle tier — worth understanding what differentiates the two.
"Good Value" is a price-based claim distinct from "Most Popular," which concerns purchasing frequency — worth reading "Good Value" as this site's own comparative statement about the 3-bottle tier's price relative to the 2-bottle option.
At $59/bottle with free shipping and the 5 bonus guides, the 3-bottle tier sits between the 2-bottle tier's $79/bottle plus shipping and the 6-bottle tier's $49/bottle — worth checking these actual figures against the label.
