That's an interesting solution. It seems to me if you have to go to a storage space to pick up you groceries you could just as well go to a grocery store to pick up your groceries, couldn't you?
At least half the convenience of Instacart for me is ordering my groceries from a computer: It allows me to plan meals, look up recipes, and check nutritional information. And using search is easier than wandering around a grocery store.
