Frequently Asked Questions
Do the two products need to use the same unit of measurement?
No — the unit label next to each product's size is just a label for display; the tool simply divides price by size for each product independently, so you can compare a price-per-ounce product against a price-per-count product as long as you understand what each unit means for your decision.
Can I compare more than two products?
Yes — click "Add Product" to add as many as you want to compare at once; the cheapest price per unit is highlighted automatically.
Does this account for quality or bulk-buying tradeoffs?
No — it purely compares price per unit of size. A lower price per unit doesn't automatically mean the best choice if you don't need that much quantity, or if quality genuinely differs between the products being compared.
