Vending machine fundraising?

[MikLast]

I have been doing my own little personal research for fundraising, and i came across the idea of vending machines as fundraisers.Before i start doing a whole bunch of stuff just to realize it will never happen, i wanted to know if other teams did this, and how they did it. I happened to find a couple sites online that offered free service (restocking, repairs, etc) but that seems a little too good to be true, and i wanted to see if anyone has experience with using this type of fundraiser.
