Y&J Cookbooks is a fictional small business owned and operated by a retired couple. Up to this time, Y&J Cookbooks has sold its books by mail order only. The owners now want to develop an online system to sell rare and out-of-print cookbooks over the Internet. Visitors will be able to browse a variety of cookbooks, but they will have to create a customer account before being able to make a purchase. Payments will be accepted only online with a major credit card, and the credit card will be verified before the order can be approved. a) Convince the owners that PayPal, Google Checkout or Amazon Payments would work as well as (or better than) directly accepting major credit cards.
