Final answer:
Cross-selling, up-selling, and bundling are marketing strategies to increase sales. Cross-selling involves suggesting additional products, up-selling involves suggesting higher-end products, and bundling offers products together at a discounted rate.
Step-by-step explanation:
Cross-selling, up-selling, and bundling are all sales strategies that are used to increase the value of a purchase. An example of cross-selling might occur in a clothing store when a salesperson suggests purchasing a belt that goes well with a pair of jeans you're buying. An example of up-selling could happen in a phone store; imagine you're there to renew your contract, and the salesperson offers you a more expensive plan with more data. With bundling, you could think of a fast-food chain offering a combo meal, which includes a burger, fries, and a drink at a discounted rate compared to buying each item separately. Although these strategies are common and legal, they can sometimes be seen as anti-competitive if they limit choices or manipulate customer purchases excessively.
