One way to do this is to offer small courses lasting no more than two hours where you teach how to use that item.

Make the demonstrations on days that you have more clients in your business so that more people see the test.

The big company Apple often uses this method and they have verified that it is a great way to increase their sales.

They usually do small workshops every so often (3 months, 6 months) that only last a couple of hours an afternoon, and show the operation of the new iPad, the new iPhone, or any other accessory that they have just launched on the market.

10. Pass out business cards

Printing some business cards will not cost you a lot of money and you can make a good professional impression with them by giving them to people who can promote your business.
