Formula
Each offer is its price divided by its quantity, rounded to the nearest cent:
Unit price = offer price / offer quantity
The result is the lower of the two unit prices. One package by itself belongs on the unit price page.
Assumptions
- The two quantities use the same kind of unit.
- A lower unit price is the offer to prefer.
Worked example
$5.00 for 10 and $8.00 for 20 have a lower unit price of $0.40.
Input definitions
- Offer A and offer B
- Two packages, each with its own price and quantity.
- Lower unit price
- The cheaper price for one unit after both offers are divided.
Limitations
Quality, brand, and a unit conversion are not judged. Compare quantities that mean the same thing.
Questions

The shared unit price is shown, and the detail says the offers match.
