I had to look at that carefully, but I think that "save you $57.65 on 33 fl oz" is both technically and meaningfully correct. It compares our best choice to the most popular choice -- we use the product with the most ratings as a proxy for that. Nizoral 2-in-1 has a crazy 100k reviews, but it is in fact almost 20x more expensive per fluid ounce! And it is the most popular product@

If you hover the text it explains the logic (you can see that in this screenshot https://imgur.com/a/hO7fiWR). But to replay the logic here:

Equate 2 in 1 Dandruff Shampoo 28.2oz is 21¢/fl oz (for 33 fl oz it costs $6.99) is the Popgot choice.

But the most popular (e.g. most reviewed) product is "Nizoral 2-in-1 Anti-Dandruff Shampoo" and that costs a whopping $1.96/fl oz (33 fl oz it costs $64.63)

So yes, the most popular anti-dandruff shampoo (which I used to use, until I saw this shampoo list https://popgot.com/shampoo?attributes=scalp_concern%3Adandru...) is literally 20x more expensive, so you can do a lot better by picking alternatives at the top of that list.

Not sure why you didn't see toilet paper, but it is right here: https://popgot.com/toilet-paper

I always kind of felt like it would be great to compare all kinds of toilet paper (soft, not soft, 1- 2- 3-ply etc) together based on weight. I feel like I use a lot fewer sheets of thicker toilet paper. So if I could see which was cheapest per gram or something I’d be pretty interested.
