We had WF delivery for a couple of years. It was great for us. But, you could tell they were trying (unsuccessfully) to monetize it. When they curtailed it they offered a pickup service as replacement: Instacart is the app for placing orders. On the whole, the pickup service works pretty well except you don't get sale prices.

I can see delivery coming back now that Amazon is in the picture. I can also see a bigger push to sell prepared foods for delivery. Prepared foods are the real money makers.
