The one major criticism I’ve always leveled at Walmart is that the chain is just too small. If they were really doing things right, all our cities would be enclosed and connected in one long continuous Walmart where all our desires can be met at everyday low prices. To edge closer to that utopia, Walmart is launching several new Facebook pages. 3,500 of them. Each is pegged to a specific local store and will serve up deals just for that store.
