About CompareUnitPrices

Pack sizes make it genuinely hard to tell which option is actually the cheaper one — the bigger box isn't always the better deal once you work out the real cost per diaper, per pod, per sheet, or per ounce. CompareUnitPrices exists to do that math for you: every listing is ranked by real, verified price per unit across every pack size and brand in its category, so the best deal is obvious at a glance instead of something you have to calculate yourself in a store aisle.

It's an independently run site, currently maintained by one person. Prices are hand-verified against the retailer's own listing pages — see the timestamp shown next to every price — while the site works toward live-updating data through official retailer APIs.

As an Amazon Associate, CompareUnitPrices earns from qualifying purchases made through links on this site, at no extra cost to you — see the Terms of Use for the full disclosure. That relationship never affects which option we show as the best per-unit value; the ranking is based purely on the numbers.
