Many products benefit from customers being shown how products are used through a demonstration. Whether the demonstration is experienced in-person or via video form, such as over the Internet, this promotional technique can produce highly effective results. Unfortunately, demonstrations are very expensive to produce. Costs involved in demonstrations include paying for the expense of the demonstrator, which can be high if the demonstrator is well-known (e.g., nationally known chef), and also paying for the space where the demonstration is given.
An in-person or personal appearance by someone of interest to the target market, such as an author, sports figure or celebrity, is another form of sales promotion capable of generating customer traffic to a physical location. However, as with demonstrations, personal appearance promotion can be expensive since the marketer normally must pay a fee for the person to appear.
