Our operators have used the SmartMart to vend many different types of products. Some operators turn the SmartMart into a vitamin and supplement shop. One operator filled their SmartMart at a dance studio with ballet shoes of various sizes for children who forget their shoes. This is your business and you can decide what revenue enhancing products you want to add.
You may not use a SmartMart in every location but you definitely want the option of adding one.
