Vending machines are definitely a nice source of income if you place them wisely. One of my buddies works for a car dealership and there is a guy that makes six-digit income with just those candy machines that cost a quarter. He just has them set up all over the place and keeps tabs on how well each one is doing. If one isn't cutting it, he pulls it and replaces. Vending machines may seem easy enough, but they are a business of their own and take the time and patience, as well as hard work, that any other type of business takes.
