I own a Vending machine.
Welcome to the business, "Flamboyant Homosexual".
For starters, no, you can't just randomly stick your machine wherever you want.
And any chain store, (Wal-Mart, Target, Smiths, Rayles, Ralphs, Duncans, etc.) will NOT let you stick your machine out front, don't even TRY.
A small, privately owned, local store MIGHT. Good luck.
ALWAYS do local places, nothing chain, nothing big, they don't care about you, Sega.
Small, privately owned, local shops.
Mechanics, Auto-Parts stores, Salons, Barbers, get where I'm going with this?
Try for construction related companies as well, IF YOU HAVE AN IN! If you know nothing about the place, DON'T EVEN TRY.
But if you have a friend or relative that works there, talk with them, and give it a shot.
Wholesale/Bulk outlets, like Sam's Club and Costco, are your best bet for Sodas.
I get mine for around 23 cents a piece.
Buy in big 32-packs.
Coca-Cola is the biggest seller in America, this is just the way it is, there is no exception.
My machine pushes 60+ Cokes per week, of the 100 or so total sales.
Charge less than anyone else.
Around here, a normal soda machine is $1.25, hotels run $2.00, schools run $1.50 - $1.75.
Based on this, I sell my flax for $1.
Charge based on your local prices.
Never run into a machine over $1? Charge 75 cents.
Rarely see a machine under $1.50? Charge $1, make a killing.
But the real magic to a vending machine is location.
The BEST place you could possibly have one, is at a hotel.
Because people will always buy.
Charge $2.50 for a can of *Can'tSayThisOnTV*ing coke, you'll sell just as many as if you charged $1.
Hotels are AMAZING in this way.
ANYWHERE ELSE, HOWEVER, YOU CANNOT PULL THIS OFF, DON'T EVEN TRY Dangit.
