Laundry, honestly
What's the cheapest laundry per fl oz we've recorded?
Downy Fabric Softener, Cool Cotton, 190 Load 140 fl oz at $0.084 per fl oz (140 fl oz, recorded price checked 2 yr ago). Prices move — every item links out to Amazon to check today's price.
Is it cheaper to buy laundry on Amazon or at the store?
For 3 of the 5 laundry items we track, the Amazon cart beat the store shelf once the trip is charged in — the drive and your time add about $14.45 to every store run before you buy anything. For the rest we either found the store winning (and we say so) or don't have shelf data yet.
How do you calculate these prices?
Every price is a recorded price from a real order or a periodic re-check, stamped with when we captured it — nothing here is scraped live. The store side of every comparison also carries the trip: 11 miles round trip at 26 mpg plus 52 minutes of your time. You can change every assumption on the trip cost calculator.
