Many companies provide guidelines for their purchasing agents on accepting gifts, samples, and favors. For example, under Walmart’s “no coffee” policy, its buyers cannot accept even a cup of coffee from a vendor. Any samples or models must be returned to vendors once a sales demonstration is complete. Other companies allow buyers to accept items of minimal value. Still others place a specific dollar limit on the value, such as $25. What problems do you see with any of these policies? What advantages do you see?
