I have only been to Costco on business, we don't have any here. I like BJ's, too. Lots of killer bargains on tons of products.
My wife used to work at one of these local places. She had to wear a button that said, "ask me about BJ's".
I hate when costco has fish or some vegetarian food on samples. Seems like a waste of MY time Best sample is a whole wing or a 1/4 angus burger
