Resources: Unit Pricing — Being a Wise Shopper

Listed below are ways that you can become a wise shopper:

  • Compare the price per unit

  • Compare brands

  • Check sales

  • Read labels

  • Check weight

  • Buy in bulk

  • Shop closer, less often

  • Use coupons

  • Shop at discount stores

But are all of them true? Often buying in bulk (or buying big boxes) saves you money, but does it always? The best way is to determine and compare the unit price. Unit means “one,” so the unit price is what one of an item you are purchasing costs. For example, a dozen (12) cookies cost $3.60. The unit price would be $3.60/12 or .30/1. Therefore, the unit price or the price for each cookie is 30¢.

Sometimes you need to compare prices. A big box of cereal (24 ounces) costs $2.48. A smaller box (12 ounces) costs $1.75. Which is the better buy?
