About Us

WDS. What makes Costco a success can make you a success
Warehouse Demo Services is the exclusive Product Demonstration company for Costco in the Northwest, Bay Area and Los Angeles Regions. We employ, train and equip energetic, friendly men and women to offer free trial samples of Costco products (some of the best in the world) to Costco members as they shop. Members not only get the benefit of the highest quality merchandise at the lowest prices, they get to try it right at the point of purchase. That’s fun and then some.

For Costco Vendors: Our business is to make your products a great success in Costco. Product sampling demonstrations allow Costco customers to experience your products before purchase and learn their most compelling benefits first hand. Enabling Costco shoppers to see your products' features demonstrated and learn how good they are for themselves at no cost or risk is the proven No.1 way to turn Costco's high volume potential into sales and long lasting brand loyalty. With two decades of experience nobody knows more about implementing effective Costco demos than we do. Let us help you design a program in the Costco Way.

For Demonstrators, WDS gives you a great opportunity to put new earnings in your pocket, while you enjoy a job that's fun, flexible and a productive career you can be proud of.
“WDS people ensure we get the most sales we can together. WDS demonstrators really sell our product equities. We get incremental sales at the point of purchase—you cannot consistently do this via an ad in a circular or handout flyer or on TV.”
