Demonstrations can create the trust and the sale
Vendors generally conduct demonstrations of kitchen appliances in exhibitions which often lead to instant sales. Many of the popular brands of water purifiers, vacuum cleaners, etc., have believed in personal selling through demos. Many of us make that difficult decision to buy our dream car only after the test drive. Free sampling that many product companies offer is nothing but a demonstration of the product features. Even hawkers know the art of luring the kids with demonstrations of the toys they are selling.
