And you are missing that I'm saying that for items I have priced that are the same size - I've found Costc to be more expensive. Which is why I leave them behind.
I've also checked some of the larger size items where after adjusting for size - the price is the same or more expensive.
Yes, I'm missing that, because you actually didn't say that.
My position is that Costo likes to have higher dollar items, and push to higher transaction amounts.
regarding unit price being higher at Costco, I haven't found that to be the case, except sometimes with the fresh meat in some cases, but there I think its fresher/higher quality.
Some of the other fresh produce might be a bit more expensive, but with dry goods, such an occurance is very rare.
