How the study works
- Load the newest validated Price Scout snapshot for laundry detergent in the disclosed reference market.
- Keep only high- or medium-confidence records with retailer source URLs and normalized unit data.
- Rank comparable rows by cost per load; package prices remain visible for checkout context.
- Disclose the reference ZIP, latest observation timestamp, and source URL for every published row.
- Stop indexing the page when the newest data becomes stale or too sparse.
What the results do not prove
- This is a current source-backed sample, not a complete national basket.
- Coupons, loyalty offers, taxes, shipping, delivery, subscriptions, and personalized promotions are not deducted.
- Package variants can differ by formula, size, flavor, scent, brand, and fulfillment method.
- Retailer source pages control the final price and availability.
Practical interpretation
What shoppers should take away
Use cost per load before trusting the shelf or package price.
Open the source record before buying because cart terms can change.
This study is strongest for laundry refill trips where load count, pods, liquid, and formulas differ.

Research FAQ
Questions about this study
Which retailer is cheapest for laundry detergent?
The live table shows the current lowest compatible source-backed unit value when enough fresh records are available. The result can change with package size, market, coupons, and fulfillment.
Why not rank by package price?
Package price can reward smaller packs. Normalized unit value makes different sizes easier to compare before the final checkout check.
Are Amazon prices included?
No. Amazon may appear as a disclosed shopping option elsewhere on Price Scout, but this research table uses retailer source records from the Price Scout price index.
