Final answer:
An example of up-selling with an alcoholic beverage would be offering a larger size or a premium brand. This technique aims to enhance the sale's profitability through upgrades or more expensive items. The foot-in-the-door technique involves starting with a small request to increase the likelihood of agreeing to larger requests later.
Step-by-step explanation:
An example of up-selling an alcoholic beverage would be option a): Offering a larger size or an upgrade to a premium brand. Up-selling is a sales technique where a seller induces the customer to purchase more expensive items, upgrades, or other add-ons in an attempt to make a more profitable sale. Offering a discount as in option b) could lead to a second order but does not constitute up-selling. Suggesting a non-alcoholic beverage or a different type of alcohol entirely, as in options c) and d), are more akin to cross-selling or changing the nature of the sale rather than up-selling within the original item category.
Using the foot-in-the-door technique, a store owner could initially recommend a small additional purchase, such as a high-quality data plan when you are buying the latest model smartphone. Agreeing to this smaller request increases the likelihood that you will consent to a higher-cost item like an extended warranty later on. This approach leverages the goodwill and compliance established through the initial agreement to encourage further purchases.
