well, from the little i researched last year on the vendin machines is...
scenario A: buy the machine through a company... they find you a location... pretty sure you stock the thing,through like buying stuff from sams etc.
scenario B: buy the machine, find your own location (HARD) and go on about yor business... stocking and taking the $$$
supposedly even a crappy one sells like...
200 sales a week@ average $1.00x 4 weeks monthly= $800 before you add in costs...
machines are like 3-4-5k... depends on model...
google it,thats what i did.
