Let me explain. Imagine you are the owner of a car dealership. A huge chunk of your profits come from the parts and services department. Not only do you want to encourage people to buy cars, but you want them to service their cars at your dealership. So you decide to give out branded emergency car kits with your logo and phone number printed on the front. Customers will not only be thankful for the jumper cables when their battery dies, but they will also know who to call to get that battery changed.
Good promotional items not only encourage sales, they build lasting relationships.
