I use Kirkland dishwashing detergent; the new formulation is comparable to Dawn, at about half the price. The older, clear formulation was not quite as nice.
I haven't tried it in several years. Like you said, the old stuff didn't meet our expectations. Is it comparable to Dawn, or Dawn Platinum? We've found that Platinum stuff to be superior to everything else. Also, how about the dishwasher detergent? Have you tried that stuff recently?
I'm using Costco pods and they are the best I've used. I don't pre rinse, I use it on old dishes. My dishes come out nice and clean. My sister cancelled her membership and now I have to find a new dishwasher pod dealer.
Gas, paper products, salad, honey, cereal, bacon, snacks, even alcohol. It's just me and my husband and we live pretty frugally. We opened a membership a few years ago and have never once regretted it.
The true answer is a bit embarrassing, but it's because my husband does our grocery shopping and he is bad with money. He will buy too much stuff because it's a "good deal" which just ends up costing more overall. I love him so much, and he has so many good qualities, but he's a real sucker for "deals" and that's all Costco is.
