It’s a lot more complex than an ordinary vending machine though. That increases costs. A curry machine is nothing more than a normal vending machine with a heater. A ramen machine is nothing more than a normal vending machine with a tap for hot water. Adjusted for inflation, the pizza machine would cost $8 for a small pizza. You can buy one from Little Caesar’s for the same price and it’s bigger and probably tastes better as well, since, as cheap at it is, the crust is at least fresh.
