Cumberland Farms, a gasoline and convenience retailer, has announced that customers have saved a total of $50 million through its SmartPay program since its launch in January 2013, according to a company press release.

Available as both a payment card and a mobile payment app, the program is free to join and free to use. SmartPay Check-Link users automatically save 10 cents on every gallon of gas, every day, when they fill up at any Cumberland Farms gas retail locations throughout the Northeast and Florida.

In addition to saving 10 cents on every gallon of gas, SmartPay mobile app users receive a free Farmhouse Blend coffee, free Chill Zone beverage, or free bottle of water for every 40 gallons of gas purchased. To date, Cumberland Farms has given away over 2.5 million free drinks via SmartPay Rewards. Cumberland Farms' major suppliers are also getting into the act, providing free coupons on a range of in-store products with SmartPay Rewards, according to the announcement.

"Three years ago, SmartPay was an entirely new concept, so it's incredible to see that we have already hit the $50 Million mark in terms of customer savings through the program," said Ari Haseotes, CEO of Cumberland Farms. "Our customers absolutely love the program, and we get thousands of new customers every week, mostly from word-of-mouth referrals by existing customers."
