A full-line vending business sets up several types of vending machines that sell a wide range of products, such as soft drinks and snacks. Soda is usually sold in 12 fl. oz. (355 ml) and 20 oz. (591 ml) in the United States and some times Australia, or 330ml and 500ml in Europe, Canada, and other areas. Snacks, bags of chips and similar edibles are usually about 1-3 oz.
In the late 1990s and early 2000s, there was a trend in the U.S. for large national retailers to have contracts with the national vending companies to provide full line vending services to all their branches' lunch / meal rooms. In most cases, managers and staff of individual stores objected to this, because the national vending companies were not necessarily responsive when making the product choices for the machines. As a result, this trend began to reverse. Most full line vending operators are independent and are small operations. Often, they can have the existing vending machines removed and get permission to install their own machines by promising to lower prices, stock the machine with the manager's favorite candies, or provide better service (e.g. servicing the machine the same day if a coin jam or bill validator becomes jammed).
For operators, soda/snack machines have the advantage that many locations recognize the need for such machines. Many locations will, in fact, take the initiative to contact a vending company to request installation of a machine. Moreover, companies recognize the difficulty in moving these machines and are less likely to request removal, unless the operator does a poor job of servicing the machine. Almost all soda and snack machines have vend counters that track how many items are sold, making it difficult for an employee to steal money. The machines themselves, being large and heavy, are difficult to steal without drawing attention, compared to most bulk vending machines.
Soda and snack machines are relatively expensive, unless they are obtained through a third-party vending program. Compared to bulk vending machines, full line vending machines take a long time to service – as much as an hour for a soda machine that is low on inventory. The product also tends to take up more space. Breakdowns are difficult to repair, due to the complexity of the machines; do-it-yourself repairs may void the warranty. The machines are difficult to move; this task may require the help of professional movers. Moreover, some locations expect a commission.
