Hi y’all! after some research i’ve decided i want to ge to to the vending business. I’m doing a niche machine in hopes of good sales. I’m looking to buy a used machine in the 2-3k range off of facebook marketplace, and I wanted to know what questions I should ask the sellers, what I need to look out for etc. Also, how would I go about calling businesses and asking if I can place my machine there. Thank you!
