Save Money on Diapers in Canada

Diaper prices change across retailers. We compare recently checked listings by price per diaper, so you can narrow your search before confirming a purchase.

Always check pack size, shipping and retailer availability before you buy.

Compare Prices

Compare the currently available listings we have checked recently, without assuming every retailer has an up-to-date price.

Know When It Was Checked

Each listing shows its own check date. If a retailer has not been checked recently, its old prices are not shown in the comparison.

Price Per Diaper

We calculate unit price from pack price and count. Membership, shipping and promotions can still change the final cost.

Understanding Price Comparisons

What does "X% cheaper" mean?

When you see a savings percentage (e.g., "40% cheaper"), it means that diaper is cheaper compared to the average price of the same brand and size at other retailers. We only show this tag when the savings is greater than 5%.

How we calculate savings

We compare a diaper's price to the average price of the same brand and size across all other retailers in our database. For example, if a Huggies Size 3 at Costco costs $0.20 per diaper while the average price elsewhere is $0.33, we'd show it as "40% cheaper".
