Company Overview

About CDS

Club Demonstration Services (CDS) is the preferred in-house event marketing provider to Costco. We offer the best person-to-person marketing services in the industry, driving sales for our customers and Costco.

CDS was born from demonstrations that first took place at Price Club. Founded in 1988, CDS today is a subsidiary of Advantage Solutions. We influence customers’ buying decisions by connecting members to brands and building consumer awareness for vendors’ products.

In 2013, CDS expanded with the acquisition of WDS in the United States. The company also continued to grow internationally. We began holding sampling events in Mexico in 1992, then in Korea, Japan, Taiwan, Australia, Spain, France, Canada and China.

We base our success on our longtime relationship with Costco, the high quality of our Sales Advisors, and our strong execution rate, resulting in increased sales and brand awareness for the vendors we support.
