Uber President and Chief Operating Officer Andrew Macdonald noted that the expansion highlights the scale the platform provides for major retailers aiming to satisfy daily consumer demand. Beyond the increased availability, the companies are introducing new incentives to attract subscribers, including specific discounts on Uber's membership service and various gift card promotions for Costco members.

This move deepens the integration between the warehouse club and the delivery giant, moving beyond simple logistics into a broader ecosystem of retail perks. By covering almost the entire country, the partnership positions both companies to compete more aggressively against dedicated grocery delivery services and regional retail chains.
