For many, coffee is a ritual—a morning wake-up call, a way to break up the afternoon at work, and a treat to enjoy with dessert after dinner. And on National Coffee Day, that ritual becomes a whole lot cheaper. On Sunday, September 29, several food and beverage brands are celebrating coffee by giving away free and highly discounted cups. 7-Eleven is offering coffee for $1 in any size; at Krispy Kreme, you can get free coffee with no purchase necessary, and try a new limited-edition product, too. Check out all of the deals we’ve found so far below, and keep checking back up until the 29th in case we find more.
