Costco Expands Same-Day Delivery With DoorDash

Costco shoppers will be able to tap into delivery for groceries and other warehouse staples through DoorDash, broadening access to the retailer’s high-volume, lower-margin assortment. That follows a year in which consumers have remained price-sensitive and more willing to compare delivery fees, ticket bundles and store-brand bargains across platforms.

The timing also underscores how delivery is becoming a bigger part of the grocery value chain. In the same way Costco has sold third-party bundles such as Disneyland tickets and deep-discount wine to draw traffic and reinforce its value image, a DoorDash tie-up lets the company add convenience without diluting its reputation for savings.

For DoorDash, the deal adds another nationally recognized retailer to its marketplace and strengthens its pitch beyond restaurant takeout. That matters as delivery companies fight to keep order growth, improve mix and defend margins against rivals including Uber Eats and Amazon-backed options.

Costco shares were last up 0.6% in recent trading, while DoorDash was little changed after a volatile run for consumer and delivery stocks. Technically, Costco’s shares are trading near the top of their recent Bollinger Band range and above the 50-day moving average, while DoorDash remains below its 200-day average even after a recent rebound, reflecting the market’s still-cautious stance on delivery economics.

The bigger takeaway is that Costco is continuing to test how far it can stretch its brand beyond the warehouse, and DoorDash is trying to prove it can monetize more than restaurant meals. Investors will watch whether the rollout lifts order frequency and basket size without pressuring Costco’s low-price identity or DoorDash’s still-fragile profitability.
