Samples for marketing.
There is nothing like actually trying a product or service out for yourself; therefore, if you experience it you know what you are buying and it may make it simpler for you to achieve your sale. You could give away a free sample, or you might decide to charge a small amount to offset the cost of the sample.
The most cost-effective way of using a sample is to make sure that it is given to people or businesses that are likely to buy your product or service. Obviously some samples are delivered door to door, are given out in stores, are sent by mail, or perhaps they are given away at trade fairs or exhibitions; this is a fairly expensive way of promoting your business. Therefore, sound advice says only give away samples to those people who are likely to buy.
If you have a service, you could give all or part of the service away for free as part of a trial. One way of making samples more compelling is to have a limited number; therefore, potential consumers or business partners will need to be proactive in order to get their sample.
