Which of the following is NOT a form of sales promotion?

A form of sales promotion typically includes short-term incentives that encourage the purchase of a product or service. Options such as coupons, free samples, and contests are all direct promotional tactics aimed at stimulating immediate sales or engagement.

Coupons are a classic example of sales promotions, providing consumers with discounts that encourage them to make a purchase. They act as a financial incentive to buy.

Free samples allow consumers to try a product without any financial commitment, directly promoting the product in the hopes of converting trial into a repeat purchase. This tactic is effectively used to generate interest and excitement around new products.

Contests create excitement and engagement, drawing consumers' attention and encouraging them to participate for a chance to win, often leading to increased product awareness and sales.

Brand loyalty programs, on the other hand, focus on long-term engagement with customers who already trust and frequent a brand. While these programs can retain customers and incentivize repeat purchases, they don’t necessarily promote sales in the short term. Instead, they foster loyalty and relationship-building, making them distinct from traditional sales promotions aimed at immediate transactions. Therefore, this approach is not categorized strictly as a form of sales promotion, making it the correct answer.
