Yeah, I know K-Mart is still in business but they are about 5% of what Wal Mart is in the big picture of things. For people who are familiar with both business models, whats the difference? Why did Wal Mart do so well, and K-Mart not? Why hasnt there been more competition for Wal Mart i.e..another large retailer opening up to take a chunk outta WMs consumer share?

I'm just curious. Share your thoughts.
