Wal-Mart Tests Same-Day Delivery – WSJ.com – Great idea, but my prediction:  This isn’t going work for Wal-Mart.  I see a brand/vision alignment issue here.  This is Walmart’s vision, “We save people money so they can live better.”  I really like that vision because it is focused on the customer and their real objectives, but it is hard for me to see how this ties to that vision unless it is executed extremely well.
