FAQ

What is priceperdiaper.com?

I'm a developer and a new parent who got tired of jumping between dozens of Amazon tabs to compare prices and sizes. I built this tool to condense everything into one view.

Instead of doing 'diaper math' yourself, you can filter by your baby's weight and see every deal’s true price per unit in a single glance. It’s designed to help parents make the right decision instantly.

Is my data safe?

We don't track you. We don't use cookies or accounts; we only show you the data.

How often is the data updated?

The data is updated every four hours.

How is the Price per Unit calculated?

We take the current listing price and divide it by the total quantity listed in the product specifications.

Do I buy products directly from this site?

No. We are a data comparison tool. When you are ready to buy, we redirect you to Amazon's secure checkout to complete your purchase.

Are these sponsored results?

Our rankings are based strictly on data. We do not accept payment to rank products higher, though we may earn a small commission if you buy through our links.

Why are some products missing?

To keep the list clean, we automatically filter out duplicates, spam, and out-of-stock items. We also focus on the top 100 highest-ranked products in each category to ensure you're seeing the most reliable options.

Why was a specific item excluded?

Our system occasionally struggles to classify niche products. These are reviewed by our team regularly. If you find a great deal we missed, please email us.

Does this include the Subscribe & Save discount?

Prices shown are for one-time purchases. Discounts from Amazon's 'Subscribe & Save' program are applied at checkout and may result in an even lower price than listed here.

What about different diaper sizes?

We track the specific size and count listed in our table. If you change the size or quantity on Amazon's page, the price per diaper will change.
