Walgreens is offering a $25 store credit to anyone who gets vaccinated at one of its pharmacy locations. To be eligible for the incentive, you’ll have to act fast. It’s only good through Saturday, June 26—and customers in Arkansas, New Jersey, and New York are not eligible.

The incentive will be given in two forms: A $25 credit to a customer’s myWalgreens account, or via a $25 gift card if they don’t have an account. Children ages 12 to 15 are not eligible for the money directly, but it will be given to their parents.

To help drive vaccinations. Walgreens says 4,000 locations have extended their pharmacy hours during Fridays in June—and walk-in appointments are welcome.

President Joe Biden had hoped to get 70% of U.S. adults at least partially vaccinated by July 4, but it now seems certain the country will fail to reach that goal. (Sorry folks, that means we probably won’t all get a free beer.) On Tuesday, the administration instead began touting that 150 million Americans are now fully vaccinated.

Officials are pressing to increase the number of people who have gotten their jabs, though, as the highly contagious Delta variant of the virus has led to new surges of COVID-19 across the globe. The variant is spreading in under-vaccinated pockets of the U.S.—and it’s growing faster in counties with lower vaccination rates than in areas that have higher rates.
