❓ Frequently Asked Questions
Is the cheapest unit price always the best deal?
Not necessarily. Consider whether you can use all of a larger quantity before it expires, and whether storage space is available.
How do stores calculate unit prices?
Stores divide the total price by the quantity. For example, a 32oz bottle for $3.99 has a unit price of $0.125/oz.
