Ricker Oil Co.’s expertise in the beverage space is all in the name. The success of the company’s fountain soda, Ricker Pop, unified a collection of c-stores under the Ricker brand about 30 years ago. Today, high-tech advancements such as branded messages on video screens at the pump help promote the soda. Even the company’s chewy ice at the fountain has a loyal following.

Beyond soda, the Anderson, Ind.-based chain has also added bean-to-cup coffee machines. The single-cup equipment uses reverse-osmosis filtered water for a fresher tasting cup of joe. Ricker’s promotes free and discounted beverages via its Ricker’s Rewards loyalty app.
