Walmart and Deliv have ended their same-day grocery delivery partnership, according to a report from Reuters.

The report cites two people familiar with the situation and says the companies stopped working together in late January, after Deliv served Walmart with a 90-day termination notice.

The move comes as Walmart has ramped up its delivery methods and options, forming partnerships with Point Pickup, Skipcart, AxleHire and Roadie in January alone. Those moves were in addition to existing deals with DoorDash and Postmates.

The Reuters report says Deliv drivers had frequent waits of more than 40 minutes to pick up orders from Walmart. Deliv operates in 1,400 cities.
