Convert all package weights to ounces before comparing dollar-per-ounce prices. Retail shelf tags may use different units, so check the heading rather than comparing their numbers directly.
What to check
| Check | What to verify |
|---|---|
| Pounds | Multiply pounds by 16. |
| Ounces | Divide price by total ounces. |
| Fees | Add mandatory purchase charges first. |
