Andrew, a resident of California, received an advertising circular in the U.S. mail announcing a new line of regional cookbooks distributed by the Every-Kind Cookbook Co. Andrew didn’t want any books and threw the circular away. Two days later, Andrew received in the mail an introductory cookbook entitled Lower Mongolian Regional Cookbook, as announced in the circular, on a “trial basis” from Every-Kind. Andrew was not interested but did not go to the trouble to return the cookbook. Every-Kind demanded payment of $20.95 for the Lower Mongolian Regional Cookbook. Discuss whether Andrew can be required to pay for the book.
