I’ve been using Whole Foods delivery on occasion for the last couple months, I like it a lot. When the pandemic first hit, they were still pretty reliable. But the last couple days they don’t show delivery windows for the next 2 to 3 days. Sometimes, if you check back later online delivery window will pop up for later that same day, or sometimes for a couple days away.
Similar delivery timing windows with Instacart.
That said, both have filled some holes in my shopping and pantry
