What? Many don't know that Sam's Club is part of Walmart? I can't believe that, they must be really ignorant. Everyone knows that. Besides, why should I drive 20 miles or more out of my way just to shop at Sam's club, when I can get the same deal at our Walmart that is less than 2 miles from my house?
On the other hand I had no idea that Costco is part of Target, but what do I care, since we don't have a Costco here. Although I think there used to be one here many years ago and in our old Mall and where Sears used to be. I remember liking shopping at Costco because you used to get good deals and the membership was reasonable.
Apparently I was in error about Costco being part of Target. But yes there are people who do not know that Sam's Club is part of Walmart.
