On my roadtrip last month, I went to see the birthplace of Walmart in Bentonville, Arkansas. There it was, the first store - Walton's 5 and 10. This little store now serves as the Walmart visitor center. Then I went to see the Walmart Headquarters. It had this big sign in front saying how much money Walmart has saved families this year. About $230 billion! But if that was how much families saved, how much money does that mean they spent at Walmart? Wow. Walmart has really grown!
