I'm thinking about entering the vending business, but I do not know which machines generate the most business. (gumball/candy and soda/snacks) I've been seeing alot of gumball and candy machines on different websites that seem very affortable. I've been thinking about purchasing a few but I do not want to go into this situation blind. If snack and soda machines generate more money this would be the route I would like to take. All I would like to know is which of these machines is the least riskiest and genearte the most revenue?
