No experience but bought a drink machine, the mech dollar type for $500; a mech snack machine for $100, sited it at my work of 15 staff plus trade counter customers an was pulling $150-200 a week. Was covenient to fill as I worked there.
Even better earnings when one of my staff was on ice or something and downed chocs and coke by the bucket load.
If you find a good site people always buy junk food. Paid for my machines within a couple of months and then pure profit for 5 years. Sold both machines on gumtree for about $1100 total.
Nice! I'm considering trying too get into abit of candy vending, It seems good as it is all mechanical, and hopefully low maintenance. All of the like triple head machines are cheap as chips.
