I picked Vitamin D as it was an option on the main page. The cheapest offered was $1.1/mg.

Costco (https://www.costco.com/p/-/kirkland-signature-extra-strength...) sells Vitamin D at less than half that price. On Amazon, the two pack of those is even cheaper.

Just an observation.

I think you've mistaken Vitamin D and Vitamin D3

The cheapest price on Pillser for D3 is $0.26/mg

That is odd. When I searched for Vitamin D, it showed me a list (which I could sort by $/mg). That list included Vitamin D, Vitamin D2 and Vitamin D3. I assumed (incorrectly it seems) that this meant that it was doing some sort of prefix match. It seems that the result table highlights the "Ingredient" column, so I assumed (incorrectly) that it was searching that column. However, it doesn't seem to search the "Supplement" column, nor is it doing a prefix match (or substring match) on the Ingredient column. This is just confusing.
