5-6 years ago, Walmart bought the vacant shopping center behind our offices and plopped down a super Walmart. So, as you could imagine, people would tend to walk over to Walmart for snacks rather than use the vending machine ($0.80 for a regular Twix in the vending machine, $0.88 for a double-size Twix at Walmart; $1.00/bag for microwave popcorn in the vending machine, $1.50 for package of 3 bags at Walmart, etc). The vending machine folks' response to declining sales: repeatedly raise their prices. The mind boggles.
