Seniors in the Class of 2020 of both high school and college can score another cool freebie to go along with their diplomas. Thanks to Pizza Hut, they can score a free one-topping medium pizza, while supplies last.

The Graduation Free Pizza Offer kicked back off this morning, and as many as a half-million pizzas will be given away. The only catch is you need to be a Hut Rewards Memberit has to be redeemed by June 4 (you sign up for a voucher).

The deal ends Thursday at midnight, or whenever the free pizza runs out.

“Our brand has a long history of celebrating moments that matter – like graduations – and Pizza Hut takes pride in being a part of our customers’ big days,” said George Felix, CMO, Pizza Hut. “So, it’s only natural that we’d be there for students and their families to help celebrate the accomplishments of the graduating class of 2020. We’re proud to partner with America’s hard-working dairy farmers to bring students who are missing out on their chance to cross the stage with their diploma, an opportunity to celebrate with their favorite Pizza Hut pizza.”

Admittedly, a medium one-topping pizza from Pizza Hut isn’t going to restore all of the memories for graduating seniors … but have you ever met one who would have turned down a free pizza at that age?
