Use cost per diaper before comparing a discount

Use enough precision

At $26.99 for 64 pieces, the listing-only cost is about$0.4217 each. Displaying just$0.42 is convenient, but a fuller intermediate value helps when comparing close offers. Our tool also shows cost per 100 diapers.

Keep the same comparison scope

Different lines, formats or sizes can have different package counts. A lower unit cost does not establish better absorption, tolerance, fit or a need to switch products.

Do not treat future rewards as current cash

A gift card earned later, a subscription or a card discount has conditions. Record that offer separately from an unconditional buy-once observation and recheck checkout.

Before you decide

• Use actual total pieces
• Keep offer conditions visible
• Do not turn price into performance
