3. This chapter has asked in several ways whether the social responsibility of the companies you patronize has ever made any difference to your purchasing decisions. Will it make any difference in the future as a result of what you have learned? Consider your last three largest purchases. Go to the Web sites of the companies that manufacture the products you bought and explore those firms' social responsibility efforts. Are they more or less than what you expected? Do your findings make a difference to you in terms of how you feel about these firms, your purchases, and/or the amount of money you spent on these items?
