Chapter 7 Exercise 5

5. Select a Web site and identify the prepurchase, purchase, and postpurchase elements.

Variable answer, almost any commercial Web site will work. Just make sure students classify features correctly. One simple example:
The site is largely focused on pre-purchase elements,with photos and descriptions of products such as calendars. The purchase step is a fairly simple shopping cart. The site does not support PayPal. Customers can create accounts or use express checkout. There is almost no post-purcahse support amd a 25% restocking fee. You can sign up for a newsletter/spam.
