Final answer:
Sales promotions are targeted activities aimed to encourage immediate purchase and are usually set for a limited time, not designed for long-term actions. Tying sales, which require purchasing an additional product, contrast with bundling, both in terms of consumer choice and potential value.
Step-by-step explanation:
Sales promotion refers to the promotional activities designed to stimulate interest, trial, or purchase by final customers. Contrary to the statement that a sales promotion activity usually lasts for an extended period without any limitation, sales promotions are typically intended for a specified period of time to create a sense of urgency and boost short-term sales. Moreover, sales promotions are not usually aimed at prompting long-term action; instead, they focus on immediate purchase behavior.
The controversial practice of tying sales occurs when a customer can buy one product only on the condition that they also purchase another product. This can force consumers to purchase items they don’t necessarily want or need and limits their options. On the other hand, bundling, which is the practice of selling multiple products or services together at a discounted rate, can offer advantages for the consumer by providing better value on the purchase of several related items.
