let me know what the cost differences are decath and selection of items...I think I went once to Sam's club and once to BJ's. - Ld------------------I have a Sams membership but I have shopped at Costco quite a few times tagging along with a couple of my friends are Costco people. I thionk Costco has a better selection, especially in the area of groceries. Prices seemed about the same to me. I would get a Costco and drop Sams except the nearest Costco is about 50 miles from here in NW Houston.
