There have been grocery delivery services for a while. Instacart, Shipt, and Doordash all do grocery delivery to many areas. Between Jan and April, when I didn't have any access to a vehicle and living out in the middle of nowhere, those were my lifelines. Fees can be a bit expensive, but it's totally worth it in many cases to let someone do the shopping and bring it to you.
Stores like Kroger, who also now owns Safeway/Albertsons (former employee), and other chains mainly do the shopping and have it ready for the drivers, or for curbside pickup. Amazon also has their Flex service which does deliver from Whole Foods, so that is a thing too. It's becoming more and more prevalent. Kroger does have a delivery service of their own, but it's still dominated by the third party services because they don't have to hire people and give them benefits.
