Frequently asked questions
What if the units differ?
g, kg, mL and L are converted automatically and compared per 100g (or 100mL).
Can I compare more than two?
Two at a time — run it again with the winner and the next product.
Does pack size matter?
That's the point — bigger packs are often, but not always, cheaper per unit.
