Sales promotion refers to short-term incentives provided to encourage the purchase of products or services. Two common techniques are:
1. Discount Offers: Companies offer products at reduced prices to attract customers.
Example: A clothing store announces a ”50% off sale” during the festive season to boost sales.
2. Free Samples: Businesses provide free samples of their products to potential customers to introduce new items or increase awareness.
Example: A cosmetic company distributes free sachets of a new shampoo at malls.
These techniques create immediate demand and help businesses compete effectively.
