📊 How the Trap Works

The unit price of bulk items is often lower. But if you throw away 30% of the product because it expires before you can use it, the true cost is actually HIGHER than buying smaller packages.

            💡 Key Insight: A cheap price per ounce means nothing if you only use half the product before it spoils.
        

💰 Real Example: Mayonnaise

Small jar (8oz): $3.99 → You use 100% → True cost: $0.50/oz
Bulk jar (32oz): $9.99 → You use only 30% before expiry → True cost: $1.04/oz
The bulk jar is actually TWICE as expensive!

🛡️ How to Fight Back

How much of this product will you realistically use before it expires? Be honest.

2. Use the Shelf Life slider

Our calculator has a "Usage" slider. Set it to the percentage you will actually use.

3. Compare true cost including spoilage

Don't just look at the price tag. Use our calculator to see the real cost after waste.
