Promotions are marketing campaigns run by merchants and shops to drive sales and attract customers. They can be in the form of discounts, special offers, bundled deals, limited time offers, contests, and more. Promotions are usually temporary and aim to create a sense of urgency or excitement around a product or service, encouraging customers to make a purchase. They can be used to clear out inventory, boost sales during slow periods, or to introduce a new product. The goal of promotions is to create a buzz and incentivize customers to take advantage of a limited-time offer.
