We went with BJ's its closest to our home, and easy in and out. We were Sam's members for a long time, and I was skeptical about switching, and boy am I very happy we did, They have tons of store coupons on a lot of different items, that most families will use...like the basic's drinks, grocery items, frozen food, bread, milk, . Also you can stack coupons using one of theirs and a manufactures coupon for even more savings. I have picked up lots books and toys for the grandkids, and they carry lots of kids clothing at least at the one I shop at..
So BJ's would be my vote.
