Ooh Wee !!!!
Just got it at costco last weekend. It is 19.99 on sale currently so this is a better deal at Amazon
I am seeing $29.99 at costco for 170 fl oz ($0.18/ fl oz), but that is the online delivery price.
BJs has it for $24.99 for 170 fl oz ($0.15/ fl oz).
That makes this Amazon deal ($0.10/fl oz) pretty good.
edit: Costco has $4 off 150 fl oz Tide Uktra Downy for $18.99 ($0.13/ fl oz)

Expensive laundry detergents use enzymes that the cheaper cleaners lack, either in entirety or in breadth. At a certain point, more enzyme doesn't improve performance meaningfully if at all. Additionally, people often use water that is too cold, or worse, too hot. Water that is too cold can affect enzyme activity, but will reducing cleaning performance all else equal. Water that is too hot can denature detergent enzymes, dramatically reducing or eliminating their activity entirely, seriously hurting cleaning performance.
I wash colors in barely cool water to avoid fading but keep temperature high enough the enzymes still work well. I wash whites in warm but not hot water, to maximize activity without denaturing the enzymes.
With cheap detergents, the warmest temperature for the clothing type is usually the highest performing it's a more straight forward temperature dependent reaction scenario.
* There is also the issue of surfactants to carry away lipid soluble contaminants from clothing. If clothing is notably soiled with fats/oils/lipids, more detergent will be required to carry it away. I sometimes add some dawn to normal detergent amounts for these jobs to reduce cost, but too much can cause foaming and problems.

Good info, but I'll add some emphasis to the last sentence here for others.
If anyone tries using Dawn dish soap I'm their washing machine, be VERY careful about the amount you use.
My roommate used too much of it in a load once and I came home to foam covering the floor and reaching out of our laundry room.
