School Savings ID, created by a student attending Chapman University, Orange, Calif., could provide students with up to a 20% discount at participating local businesses.

Business major Jason Cunningham started the service early this year to help connect local businesses with the university community. “It’s a win-win for both the businesses who participate…and the students,” he said. “Businesses enlarge their customer base and students can purchase goods and services locally on a student budget.”

It costs businesses $40 to participate. For that, they’re listed on the School ID Savings Web site and promoted through social media, campus flyers and word of mouth.

So far, 20 businesses, from taxi services and dry cleaners to yoga studios and restaurants, have signed up, offering discounts from 10% to 20%.

All students and faculty have to do to claim their discount is present their student ID.
