The subscription is available to members of MyPanera, the chain's free loyalty program and you can sign up via the Panera website as well as through their app.
The new coffee subscription covers one cup of drip hot coffee, hot tea, or iced coffee every two hours during regular bakery-cafe hours, and includes free refills of the same beverage at participating locations. It does not cover cold brew iced coffee, espresso, and cappuccino drinks.
The price of the subscription amounts to buying about four cups of coffee from the chain (prices vary with location).
