Other areas have had this already but Meijer's is set to start up "drive-through" grocery service in Chicago. A "personal shopper" picks and packs your food; you drive up and pay.
Good idea if you're short on time but... if you're picky - do you want to buy something you haven't seen? What if that meat has more fat than you like? Or you want to squeeze the fruit first? It just seems hard to buy sight unseen, at least when it comes to food.
Would you want to shop this way?
