The lead designer for Homegrocer (Amazon Fresh but too early) was in my social circle, friend of my friends, and the part he didn’t like about his job was that you still had to push the high margin items that the grocery stores put in easy reach to get your visit to be profitable to them. So there’s a moral hazard for things like search filters and sorting. As a customer I’d love to sort by price per unit. But they don’t want that (look at how many items are priced per pound in one size and per ounce in another).
