Soda vending machines need to be durable enough to withstand years of usage and abuse while still looking as attractive as they did the day they were installed. For that reason, it's very important that you properly research before coming to a decision as to which model you will buy for your business. Customers and employees alike will be using the machine, making it a valuable and profitable investment -- and it doesn't even take that long to earn the money back, even less time than snack vending machines.
The machine most seen on street corners and outside or inside stores is the type with a large picture of the products available on the front with the actual vending mechanism on the left side of the machine. These are great to entice customers and since they are large advertisements in themselves for themselves they are little to no hassle. The downside to these is that they are older models and usually do not come with any frills. Most modern soda vending machines can display or print recent sales history, while these older models can not.
You may want to have drinks available in your machines with different prices. While all vending machines must have either cans or bottles, there is no limit to products if you do not have a contract. Appropriately pricing certain drinks to demand and popularity can raise machine profits, and if you lower them they can also increase machine usage. This feature is not available on a wide selection of models, but it does come standard in a few.
Another feature that many people overlook is the LED screen. Older or cheaper machines do not have the LED screen, which can display pricing, promotional phrases, and how much change has been put in towards a particular purchase. The choice of whether to purchase soda vending machines with the screen is entirely up to you. It is a small convenient feature, but in general it does not boost sales or may consumers like the machines any more than they already do.
Get creative when choosing a machine and don't be afraid to be different. Consumers love to see something new, and they love to try out machines they have never dealt with before. Think about your area's consumer base and decide what type of machine you think would do well at your store. Also consider what other retail locations in your area have in the way of vending machines and determine whether you want the same or different styles from theirs. Deciding on soda vending machines is much more difficult than it sounds, but once they are installed and pulling in money for years to come you will not regret it.
