The second option is to co-operate a machine with a vendor. This means leasing or renting a machine for a small fee. The responsibilities of running the machine is negotiated, but the bulk of the labor is left to you. Another stipulation is that you must purchase all products from the vending machine provider. Not suprisingly, the prices for these products will be slightly inflated.
Some vendors also require a certain amount in purchases.

The third option is to purchase a vending machine outright. You have the complete freedom to offer whatever product you want and determine how much to charge.
