Why Unit Price Matters

Bigger isn’t always cheaper. A 64 oz juice at $4.99 might cost more per oz than a 32 oz at $2.49. 87% of shoppers ignore unit price and overpay.

Pro Tips for Smart Shopping

  • Check shelf tags: Most stores show unit price.
  • Compare same units: Convert lb to oz if needed.
  • Use with Discount Calculator for sale items.
  • Bulk isn’t always better: Check expiration dates.

Common Unit Conversions

  • 1 lb = 16 oz
  • 1 kg = 1000 g
  • 1 L = 1000 ml
  • 1 gallon = 128 fl oz

Grocery vs Online Shopping

Grocery: Check weight on package.
Online: Use “per unit” filters on Amazon, Walmart.

Bulk Buy Myths

Not all bulk is cheaper. A 5 lb rice bag at $8 might be $1.80/lb — but a 2 lb at $3.20 could be $1.60/lb.
