I will brave the downvotes and say: I don’t like Costco.
It’s not out of snobbishness, their quality is excellent at excellent prices.
My problem is that I find I spend more at Costco than at conventional grocery stores like Trader Joe’s.
The paradox is, it’s cheaper, but I spend more. I buy things I wouldn’t normally buy, and ant higher quantities. Even worse, I somehow eat it all quite quickly.
I spend more and eat more when I shop at Costco.
Unfortunately that’s neither healthy for my wallet nor for my waistline.
I love Costco, but I get it. My wife and I always joke about how we can't leave without spending at least $100, and how that's only like 7 items sometimes.
We didn’t have Costco in our area when I was a kid, but iirc that’s why my parents stopped going to Sam’s Club: any money they saved on buying cheaper bulk things went into buying random extras.
