What is a stated discount on a final selling price that retailers handle?

The correct answer is a "Coupon." A coupon is a specific type of discount that retailers use to encourage customers to make a purchase. It represents a stated discount amount that can be applied to the final selling price of a product. Coupons can be distributed in various forms, such as physical pieces of paper, digital codes, or through promotional offers in websites or apps. They are often used as a marketing tool to boost sales and attract more customers by enticing them to spend money on discounted items.

In contrast, the other options do not perfectly fit the definition of a stated discount on a final selling price that retailers handle. A discount can refer generally to any reduction in price, but it isn't always specifically tied to a direct retailing mechanism like a coupon. A markdown typically refers to a permanent price reduction on an item that is indicated directly by changing the price tag, rather than through a promotional offer. A rebate is a deferred discount given back to the buyer after the purchase is made, which may not provide immediate savings at the point of sale in the same way that a coupon does.
