Several years ago, Clark issued warnings over the air about vending machine scams going on out there. Well, apparently, that scam is back, according to Newsday. Ads run in newspapers and on the Web, claiming that these are “business opportunities” that will make you up to $800 a day in side income. The organizers say they find highly-populated companies that need machines and they tell you how many you need. One man bought 60 vending machines for $15,000, and the company places them. After eight months, he made less than $100 a week and the machines are now sitting in his garage. Clark thought this scam was over, but it’s actually growing again. If you believe you can make money off vending machines, buy them one at a time and see how each one does. Costco Wholesale sells machines one at a time and they are legitimate. If you have success, you can buy another and then another.
