Refer to the passage below to answer the questions that follow.
Proactive Solution is a skincare system to help people with acne. Proactive was originally sold only through direct marketing. The consumer had to enroll in the Proactive Solution Clear Skin Club. However, now some large malls have kiosks selling Proactive Solution products without the club membership, but the prices are much higher. Proactive Solution has had one of the longest-running infomercials on television, and its product line is also sold through magazine ads. Through these mediums, consumers can purchase the product directly by calling, mailing, or going through the Internet to submit an order.
-What do you think Proactive Solution uses to track consumer purchases? How can they use this to restart customers who have joined the club but later quit?
