Walmart Inc.'s (WMT - Get Report) race to catch up to e-retailer Amazon.com Inc. (AMZN - Get Report) was tripped up after the company confirmed that it was no longer working with Google-backed same-day delivery service Deliv.
Deliv was one of Walmart's first partners when the retail giant started experimenting with same-day delivery services in an effort to take back some of the business that Amazon has garnered in recent years through its Amazon Prime same-day delivery apparatus.
Deliv uses gig drivers to operate its grocery delivery service. The company operates in 1,400 U.S. cities and has partnerships with retailers like Home Depot Inc. (HD - Get Report) and Kohl's Corp. (KSS - Get Report) .
However, sources told Reuters that Deliv drivers had to frequently wait 40 minutes or more to collect grocery orders when they showed up at Walmart stores to pick up their deliveries, mostly because Walmart would place more importance on customers shopping in stores.
Walmart told Reuters that it still partners with seven other delivery firms, including DoorDash and Postmates.
Same-day grocery delivery service is currently available in 800 of Walmart's more than 5,000 stores with plans to add another 800 more this year, according to Walmart.
