Frequently asked questions
What units can I compare?
Any — as long as the items share a unit. Enter the size (oz, g, ml, L, items) and the price; the per-unit cost is computed and the cheapest is flagged.
Can I compare more than two products?
Yes — add as many rows as you like; they are all ranked by price per unit.
Is my data saved?
No — it is calculated in your browser only.
