Lots of stores are closing individual locations because more and more people are shopping on line. Same for Staples and other types of stores. That doesn't mean the whole chain is closing, and it doesn't mean that there won't be other stores providing the same products. Sam's Club is part of Walmart, which is taking a lot of heat for not paying workers a living wage. So they've lost a lot of customers who refuse to support them. But Costco has similar products (and the same or greater savings) while paying far above minimum wage and offering benefits - so a lot of people prefer to spend their dollars there. If you look around, you will find many alternatives.
And again, as you've been told on your prior posts, you're not going to get nearly as many responses because you don't put the subject of your question in the title. If you had put "Sears and Sam's closing in Georgia?" as the title, you would get 3 times as many responses. I think you are still having trouble figuring out how Mamapedia works so you can get real benefit.
