Walmart deductions get attention because the volume is obvious. The portal is active. The dollars are visible. The chargeback codes are familiar. If you are a Consumer Packaged Goods supplier doing meaningful business with Walmart, it is easy to believe that Walmart is the deduction problem. But that is usually not the whole story.
