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 a YouTube video, this promotional technique can produce highly effective results. Unfortunately, demonstrations are often expensive to arrange. Costs involved in delivering demonstrations include paying the expense of the demonstrator, which can be high if the demonstrator is well-known (e.g., nationally known chef), setup costs, and payment 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 costly since the marketer normally must pay a fee and possibly travel expenses for the person to appear.
