If you have a larger display in a more prominent location, you could sell a dozen or two. If you devote a major space in your booth to the display and take time to talk to people, showing samples and demonstrating how the product works, you could sell several hundred dollars worth. The most important factor is you, and how hard you work to sell . I have a booth in a mall. We have very good sales in many malls.
Sales are dependent on the effectiveness of the display and the amount of traffic through the mall.
Notes or signs telling what was done to the piece, how the product was applied, or ways you have used it, are all helpful. We also have available a video, consisting of 3 minute repeating segments, in which John describes the products and their uses. In a high-traffic location you will find that this greatly increases sales. If you decide to devote a video machine to this purpose, we will furnish the tape at no charge. Then, once you have gotten the customer's attention, what is shown in the display must convince them that this is a product they want to buy.
