About Us

WDS. What makes Costco a success can make you a success
Warehouse Demo Services is the in-house 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 demonstrations create trial like no other form of marketing investment can. WDS demos are the No. 1 way to turn Costco’s high volume potential into sales and long lasting brand loyalty. And nobody knows more about that than we do. With almost two decades of experience in Costco, we can help you design a demo program in the Costco Way.

For Demonstrators, we offer a great job opportunity that puts earnings in your pocket and fun, flexibility and more future in your life.
“The work that we’ve done with WDS has been very positive. It’s a great way to build your business and we certainly have built a significant business just from Costco thanks to demos.”
