The fairest benchmark on the page is the $79 regular price. Here is what each pack saves against it.
Two bottles at $79 cost $158, the same as the pack price, so no saving. Three bottles would be $237 against the pack price of $207, saving $30. Six bottles would be $474 against $294, saving $180.
That is much smaller than the saving implied by the was prices, but it is the one that matches the page's own regular price.
Using the regular price as your yardstick stops the large struck-through numbers from anchoring your decision. It also shows that the real incentive to buy more is the lower daily cost, with the trade-off that more money is committed before the 60-day guarantee ends.
