If you want to hear about a high grocery bill ask someone who is on a gluten free diet. Wheat is the cheapest thing there is and when you have to have a gluten free substitute for it then you are talking about $5 a loaf of bread no matter if you bake it or buy it, even if you mix your "flour" mixture or buy that. Baking all of your own crackers, pasta, pretzels, etc. or shopping so carefully to buy only meats, sausage, hams, canned veggies, etc. that is processed with no flour what so ever in the process (even if it is not in the food, flour is frequently used to keep machinery non-sticky) is a very time consuming and expensive procedure. Usually most products have to come from speciality stores. This diet will make the grocery bill of a normal diet, even using pre-packaged products, seem cheap! Some cities have better stocked gluten free sections than other cities, but towns seldom have much at all.
