When you start out with candy vending machines, it can be a little tricky trying to figure out how much candy you should allow to be vended at a time. You want to keep your profit margin high, but you also need to keep the customer satisfied so they don’t feel ripped off and become a returning customer. Here is a list of recommended amounts to vend different types of popular bulk vending candy:

Peanut M&M’s: 8-10 pieces

Plain M&M’s: 12-14 pieces

Runts: 10-12 pieces

Skittles: 12-14 pieces

Reese’s Pieces: 12-14 pieces

Mike & Ikes: 6-8 pieces

Hot Tamales: 6-8 pieces

Chiclets and Gum Tabs: 10-12 pieces

Cashews: 10-12 pieces

Pistachios: 10-12 pieces

This is merely a RECOMMENDATION to give you an idea, don’t feel like you’re stuck to this. Experiment and decide what works best for your locations!
