Frequently asked
What unit should I use?
Whatever's printed on the packages you're comparing — oz, lb, g, kg, fl oz, count, sheet, load. As long as every row uses the same unit, the ranking is meaningful.
Can I compare different units?
Not directly — 12 oz and 500 g need to be converted first. Use our Unit Converter to bring them into the same unit, then paste the numbers here.
Why does the "best deal" sometimes not match the biggest package?
Bulk isn't always cheaper. Warehouse stores occasionally price larger packs higher per unit than the same store's medium size — that's exactly what this tool is designed to catch.
