Frequently Asked Questions
How do I compare products with different units?
Only compare items with the same unit (both in oz, or both in grams). To compare a 12 oz can to a 2 lb bag: convert 2 lb to 32 oz, then compare price per oz. The calculator supports same-unit comparisons — make sure to select consistent units.
Why doesn’t the biggest size always have the best unit price?
It usually does for staples like rice, toilet paper, and cleaning products. But for perishables, the unit price advantage disappears if you can’t use the product before it expires. Buy the best unit price you can actually use.
