Unit price = Total Price / Quantity. The lower the unit price, the better the value.

Tips for smart shopping:

  - Always compare unit prices, not just total prices

  - Bigger is not always cheaper - sometimes smaller packages are on sale

  - Store brands almost always have a lower unit price than name brands

  - Check unit prices on shelf tags in most grocery stores

  - Consider if you will actually use a larger quantity before it expires

## Frequently Asked Questions

**Q: Is buying in bulk always cheaper?**

A: Not always. While bulk packages often have a lower unit price, store brands in regular sizes can sometimes beat bulk name-brand prices. Also consider storage space, expiration dates, and whether you will actually consume the larger quantity.

**Q: Where can I find unit prices in the store?**

A: Most US grocery stores are required to display unit prices on shelf tags. Look for the smaller print showing price per ounce, per count, or per fluid ounce. This makes comparison easy without a calculator, but the units are not always consistent between products.

**Q: Should I compare by weight or by count?**

A: For consistent items (like paper towels or trash bags), compare by count. For food and beverages, compare by weight (ounces, grams) or volume (fluid ounces, liters). Make sure you are comparing the same unit type for both products.

**Q: How much can I save with unit price shopping?**

A: Studies show that consistently choosing the lowest unit price option can save 20-40% on grocery bills. The savings add up significantly over time, especially on frequently purchased items like milk, bread, cereal, and cleaning products.
