Vending, good business idea or no?

Dude, I was just there, she showed me what they used to sell, theyve had weeks where theyve sold over 300 of them in a week WHEN they were THAT price… I am an extreme gym rat and am there all the time, I RARELY EVER see anyone with there own drinks actually which DOES surprise me… Another thing is that these numbers ARE only an estimate and I have an entirely seperate business that I do VERY well with, money makes money and I’d rather use my money then let it sit, as long as I make a profit im happy.
