This guide is being written. Here is what it will cover.

The problem it solves

Sale tags show the package price. The cheaper package is sometimes the worse unit price.

What the guide will cover

  1. Find the unit price on the shelf tag
  2. Do the division when the tag is missing
  3. Store brands as a test, not a rule
  4. Items where unit price is the wrong comparison
