Amazon Fresh, in contrast, is my primary source of groceries. Unlike Instacart, prices are consistently reasonable, the website actually knows what's in inventory so I don't have to make backup plans for everything I'm trying to get, and when I buy frozen foods, I get handy chunks of dry ice that I can use to make homemade smoke machines. Amazon Fresh is the first service I've ever used--and this includes previous incarnations of Amazon Fresh--that makes me seriously wonder whether I will ever make a trip to the grocery store again.
