Krispy Kreme is celebrating the beginning of pumpkin spice season the best way they know how—the company is giving away free Pumpkin Spice Cake Donuts all day on Tuesday, Sept. 18.

Here’s the catch: You have to be a Krispy Kreme Rewards Member to claim your prize. All you have to do is download the app. If you’re not a rewards member, you can still snag your doughnut with any purchase.

If you miss your chance for a freebie, don’t worry. Krispy Kreme’s Pumpkin Spice Cake Doughnut, described in a 2014 press release as a “moist, old-fashioned pumpkin spice flavored cake doughnut coated in Krispy Kreme’s signature glaze,” will be available through mid-November.
