Final answer:
Tying sales is a sales technique that involves requiring customers to purchase a related product along with what they are already buying. This technique can force consumers to buy something they may not actually want or need.
Step-by-step explanation:
Tying sales is a sales technique used to get a customer to spend more by purchasing a related product along with the item they are already buying. It involves requiring the customer to buy one product only if they also buy another product. This technique is controversial because it can force consumers to purchase a product they may not actually want or need. An example would be if a customer is buying a digital camera, the store may require them to also purchase a memory card.
Another related concept is bundling, where two or more products are sold together as one. Bundling typically offers an advantage for the consumer by allowing them to acquire multiple products or services for a better price. For example, some cable companies offer bundles that include cable, internet, and a phone line at a special price. Customers can choose to buy these products separately, but the bundled price is usually more appealing.
