Sprint wants you to show some serious back-to-school spirit! We're giving away more than $100,000 to lucky, eligible K-12 schools and/or PTAs. And the local community can help determine the winners! By visiting select Sprint stores Friday, Aug. 9, through Sunday, Aug. 11, parents, students and others can cast a vote for a local K-12 school they want to win $5,000. No purchase is necessary to participate.
