What technique does an advertisement utilize if it underlines the urgency of purchasing before a deadline?

The technique that emphasizes the urgency of making a purchase before a deadline is known as a Bargain Appeal. This strategy plays on the idea that consumers might miss out on a great deal or special offer if they do not act quickly. By creating a sense of urgency, advertisers encourage immediate consumer action, as people are often motivated by the fear of missing an opportunity, which can be particularly effective in driving quick sales.

In the context of other options, while Appeal to Pity seeks to evoke emotions and sympathy, and Folksy Appeal relates to familiarity and relatability, neither directly addresses the pressing need to act quickly that is central to a Bargain Appeal. Appeal to Prestige aims to associate products with status and high quality, but it does not emphasize urgency or time-sensitive purchasing. Hence, the primary focus on time-limited offers aligns distinctly with the concept of Bargain Appeal.
