Costco is teaming up with student discount app UNiDAYS to bring students and teachers a little extra incentive to join. Students who sign up for a new $65 Gold Star membership get a $20 digital Costco gift card, while teachers and faculty who start a new $130 Executive Membership get a $40 gift card. To get in on the deal, all you need is to show proof of enrollment, sign up for auto-renewal, and have a little patience waiting for your membership cards and gift card email to arrive. Members get two cards for shopping in-store or online and have the option to have orders delivered right to campus. It’s a sweet perk that makes it a bit easier to stock up on bulk snacks, dorm essentials, or some late-night frozen pizza rolls without breaking the bank.
