Where to situate vending machines to make some profit?

I have a few vending machines and I could use some extra cash but I don't know where to take them and put them to work... how can I find out where they would be needing any?

anywhere there is a lot of people walking by that would use what you have in your vending machine. Colleges, downtown businesses, malls, etc. You might even make a pitch to the businesses by giving them a percentage of your sales, try non profit organizations or charity organizations - have them put your vending machine on their property and you will give them a percentage of your sales (win/win)

If I were you and I had a few vending machines (soda, candy, gumballs, etc.) I'd solicit directly to business owners who might be interested in such services. You have to do some marketing to find these business or property owners, and send them a letter, or flyers briefly introducing your services, and explaining to them how it can be a win win situation. Then, hopefully they'll call you, or you can follow up by calling them. If all you have is say 4, machines, by sending out, say 1000 letters, you might be able to lease all four on a month to month basis!
