Cost per day is the fairest way to compare packages. This is our arithmetic, not a figure from the seller.
2 bottles: $158 divided by 60 days is about $2.63 a day. 3 bottles: $207 divided by 90 days is about $2.30. 6 bottles: $294 divided by 180 days is about $1.63.
These rely on the page's supply labels. The page does not publish per-gummy amounts, so the labels are what we have.
It ignores tax, if any, and assumes you finish the supply. If you stop at day 60, the cost of a 6-bottle bundle per day of use is much higher, because you paid for 180 days. Cost per day is only meaningful if you will actually use it.
