Costco and Epsilon: Using retail media to drive business and member value

Costco’s retail media strategy starts with what makes the brand unique—its members. In this conversation, Mark Williamson, Assistant VP of Retail Media at Costco, talks with Epsilon Retail Media's Austin Leonard about how the warehouse club is using retail media to fuel growth, drive member value and keep the “treasure hunt” alive.

“Epsilon has been a great partner to help us accelerate our offsite ambition, whether it’s through CORE ID or through private exchange,” shared Mark.

From in-warehouse signage to personalized offsite ads, every touchpoint is backed by rich member data and a deep commitment to relevance. With Epsilon’s CORE ID and turnkey solutions, Costco is scaling its reach beyond the warehouse—while ensuring that every media dollar delivers measurable impact for brands and more value for members.
