What kind of information does a 'coupon' typically provide?

A coupon typically provides a discount or offer that can be redeemed for a purchase, making it a key marketing tool for businesses to incentivize consumers. This form of information is designed to encourage potential buyers to take action—such as visiting a store or making an online purchase—by presenting them with a financial benefit. Coupons may specify a percentage off the total price, a fixed amount off, a buy-one-get-one-free offer, or other promotions that make products more appealing to consumers. This direct monetary incentive plays a crucial role in influencing consumer behavior and driving sales, which is why it is considered the main purpose of a coupon. The other options do not accurately reflect the primary function of a coupon: they either focus on unrelated information about products, advertising, or customer feedback rather than the promotional aspect.
