The bargaining power of buyers also increases when their switching costs are low. Having multiple suppliers of a product category located close to its headquarters allows Walmart to demand further price cuts and quality improvements because it can easily switch from one supplier to the next. This threat is even more pronounced if the products are non- differentiated commodities from the consumers’ perspective. For example, Walmart can easily switch from Rubbermaid plastic containers to Sterlite containers by offering more shelf space to the producer that offers the greatest price cut or quality improvement.
