Which of the following offers could enhance the effectiveness of an ad?

A huge discount can significantly enhance the effectiveness of an ad by appealing directly to consumers' desire for value and savings. Discounts create a sense of urgency and can motivate potential customers to make a purchase sooner rather than later. It captures attention by clearly communicating the financial benefit that consumers would receive, which can lead to increased engagement with the ad and higher conversion rates.

Offering a discount also helps to differentiate a product from competitors that may not be providing similar deals at that time, thereby making the ad more compelling. While other options like free shipping or information about competition can also be effective, the immediate and tangible nature of a discount often resonates more strongly with consumers, prompting them to act quickly. This strategy is common in sales campaigns and promotions to drive traffic and boost sales.
