It's interesting watching discussions about this from the UK. The last stat I can find was that around 25% of people do some or all of their grocery shopping online. Most of the time it works really well. Here, most of the supermarkets now do their online fullfillment from warehouses, not the shop floor, using purpose built delivery vehicals. One, Ocado (who are doing amazing tech work with robots and planning) are entirely online, while also whitelabelling their logistics for another supermarket. On the whole the quality is perfect, it's not "bottom of the barrel", fruit is fresh, things tend to have long dates on them. While you do get substitutions from time to time, they seem to have got rarer as they have got better at predicting demand. The main downside for my wife, who insists on shopping in person, is that you don't get the really good deals on stuff, as it's always on the short-dated stuff they want to get off the shelves.
