Final answer:
The goal of offering complementing products during a sale is to increase the value for the customer, not necessarily to get more money from them immediately.
Step-by-step explanation:
When a company offers complementing products during a sale, the fundamental goal is not primarily about getting more money from the customer, but rather about providing additional value. By doing this, businesses aim to enhance the customer's experience and satisfaction, potentially leading to increased customer loyalty and future sales. The correct answer to the question is, therefore, 'Offering complementing products during a sale is not fundamentally about getting more money from the customer.'
