Target is bringing back its back-to-school teacher discount for two weeks.

For the fourth year, the retailer will offer educators 15% off select classroom supplies and essentials in-store and online starting Sunday and through July 31, officials shared with USA TODAY. Last year, the teacher savings lasted six weeks amid the COVID-19 pandemic.

The discount, which can be redeemed only once during Target’s Teacher Prep Event, is for "K-12 teachers, homeschool teachers, teachers working at daycare centers and early childhood learning centers, university or college professors and vocational/trade/technical school teachers."

But to save, teachers need to verify their eligibility through the Target Circle loyalty program.
