Dawn Ultra 51.5 oz Jug Is $8.05 Live — The 2.64 L Refill Hits $20.49, 47% More Per Ounce, While Our Catalog Says $11.84
Live Amazon.com from Chicago: the Dawn Ultra 51.5 oz refill jug is $8.05 ($0.16/fl oz) from Amazon, while the 2.64 L refill is $20.49 ($0.23/fl oz) from a third-party seller. Two jugs cost $4.39 less than one big bottle and hold more soap. Our catalog cards still say $12.95 and $11.84.

Verdict: The Dawn Ultra 51.5 oz refill jug is $8.05 live on Amazon.com, which is $0.16 per fluid ounce. The Dawn Ultra 2.64 L refill is $20.49 live, or $0.23 per fluid ounce, and it is sold and shipped by a third-party seller, not Amazon. The bigger bottle costs about 47% more per ounce. Two of the 51.5 oz jugs give you 103 oz for $16.10. The 2.64 L bottle gives you 89.2 oz for $20.49. That's 13.8 more ounces for $4.39 less. Our catalog has both cards backwards right now: the jug still says $12.95 and the 2.64 L still says $11.84. If you went by our cards, you'd buy the wrong one.
I cover value and budget buys from Chicago, and I checked both pages with a Chicago 60601 delivery address this morning. I'm not running a grease test or counting how many dishes a squirt cleans. Same brand, same Dawn Ultra line, same blue soap. The only question here is how much you pay per ounce, and the answer is not the one you'd guess.
What it is
Both listings are Dawn Ultra dish soap refills, meant for topping up the smaller bottle by your sink.
The 51.5 oz jug (B0FX5X647R) is the Original Blue refill jug with a pour spout and handle. Live one-time price $8.05 ($0.16/fl oz). Subscribe & Save shows $7.65 ($0.15/fl oz). Shipped and sold by Amazon.com, In Stock, 4.8 stars from 126,008 ratings, and the page says 20K+ bought in past week. It's #26 in all of Health & Household. Our catalog card says $12.95, which is stale by $4.90.
The 2.64 L refill (B09SNR3CDV) is Dawn Ultra Original Scent in a liter-labeled bottle. Amazon's product table lists it as 89.2 fl oz. Live one-time price $20.49 ($0.23/fl oz), shown against a $22.80 list price. The buy box is forestcity1, a third-party seller that both sells and ships it, and a second offer on the page was even higher at $23.80. In Stock, 4.7 stars from 27,171 ratings, 50+ bought in past week. Our catalog card says $11.84. That number would make it the cheapest Dawn per ounce on the site, and it isn't anywhere close today.
Who it's for
Buy the 51.5 oz jug at $8.05 if you wash dishes by hand most days and want the cheapest Dawn per ounce I found today. If you go through soap fast, buy two. You still spend less than one 2.64 L bottle and get more soap. If you reorder on a schedule anyway, the $7.65 Subscribe & Save price knocks it down to $0.15/oz.
Buy the 2.64 L bottle at $20.49 only if you really want one single bottle on the shelf instead of two jugs, and you're OK paying about $6.55 more than the jug rate for the same 89.2 oz. I couldn't come up with a better reason than that.
Who should skip
Skip the 2.64 L listing if you're buying it because "bigger is cheaper." Today it isn't. Skip the jug as a lone order if you don't have Prime and aren't adding anything else to the cart. The page says free delivery applies to orders shipped by Amazon over $35, and an $8.05 jug by itself doesn't get there. Put it in with your next paper-towel or trash-bag run.
Honest nits
- Our catalog is wrong on both cards. The jug is $8.05, not $12.95. The 2.64 L is $20.49, not $11.84. Always check the live per-ounce number Amazon prints under the price.
- Third-party seller on the big bottle. The 2.64 L buy box is forestcity1, not Amazon. Seller prices move more, and returns go through that seller's terms. Look at who's selling before you click.
- The liter label. The 2.64 L bottle is labeled in liters, not ounces. Amazon converts it to 89.2 fl oz for you, so use that number when you do the math.
- Slower delivery on the big one. When I checked, the 2.64 L showed free delivery October 15–16, and the jug showed Monday, October 12 for Amazon-shipped orders over $35.
- No fake dish-count chart. How long a jug lasts depends on how many people eat at your place and how heavy your hand is with the squeeze bottle. I won't make up a number of dishes per ounce.
Value verdict
Buy the $8.05 Dawn Ultra 51.5 oz jug. At $0.16/oz from Amazon.com it beats the 2.64 L bottle by about 47% per ounce, and two jugs still cost $4.39 less than one big bottle for more soap. Skip the $20.49 2.64 L refill unless that exact bottle matters to you. And don't trust our $11.84 card on it until it updates.
Is one bottle instead of two worth an extra seven cents an ounce? Not on my budget.
