Good to know
- Weights are compared in grams, volumes in milliliters, and pieces per piece — mixed types (for example grams vs liters) cannot be compared.
- For weights you get the price per 100 g and per kg; for volumes the price per liter; for pieces the price per piece.
- A lower unit price means the better deal only when quality is similar — taste and brand quality matter too.
- Bulk is usually cheaper per unit, but only buy what you will use before it expires.
