Beyoncé and Jay-Z are offering vegan fans the chance to win 30 years worth of free tickets to their shows through a partnership with The Greenprint Project, a program that encourages plant-based diets with the help of a digital tool, a book, a documentary, and a clinical trial. Beyoncé announced the contest on her Instagram account.

Although both her caption and the contest entry say that fans (U.S. residents 18 and older only) can win a lifetime supply of tickets, the fine print actually defines life as “up to 30 years.” The chosen one will win a pair of tickets to one Beyonce and/or Jay-Z concert per official, scheduled tour for the next 30 years. This excludes performances at any scheduled festivals that are not part of the listed tour dates on Beyonce and/or Jay-Z’s official websites.

To enter, all you have to do is enter your name and email address on The Greenprint Project’s website, so technically, no one is checking if you’ve actually gone vegan, but the website provides guidance if you wish to do so. Visitors to the site can click a drop-down menu and select which plant-based diet they want help shifting to, such as “All plants. All the time,” “Plant-based for breakfast,” “Plant-based at work,” “Two plant-based meals a day,” “Meatless Mondays,” or “Plant-based on week days.”

The last day to enter the contest is April 22, and the winner will be selected at random on May 22.
