Consumers’ love for the 90s runs deep, not just for the pop culture and aesthetics, but also a longing for the era’s refreshingly low prices—and this summer, Instacart’s Summer Like It’s ‘99 campaign was created to help people relive the magic of the decade with throwback prices.

The campaign, informed by a tough economy and “economic nostalgia,” sees prices for 90s favorites like Kool-Aid, Kraft Mac & Cheese, and Capri Sun slashed by 47.2% to match their 1999 cost.

Instacart is planning its largest in-person consumer event to date. This September, it will host a free, first-come, first-served concert with Third Eye Blind at NYC’s Terminal 5. Adults can expect to sip 90s-themed cocktails, kick back in bean bag lounges, and enjoy experiences from brand partners, like Frosted Flakes’ tip-frosting station.
