The Evil Daughter-in-law of the Farmer Became a Good Person

Doesn't the heroine have her own supermarket? Since the supermarkets even have medicinal materials, how about the most indispensable rice? Do you want to go to town to buy it? Since I don't have any money, shouldn't I save some money in the early stage? Do you have to eat polished rice? Brown rice, millet, etc. Are not nutritious? Are whole grains nutritionally worse than polished rice? To put it bluntly, rice tastes good, and its nutritional content is only sugar and starch. There is so much food in the supermarket in your own space, why waste money on buying it? That's a supermarket, not a canteen, right? What doesn't the supermarket have? I have seen a story where the heroine followed the house through time. What was in the house before was automatically replenished after use. The things in the house are limited, but there are many things sold in this supermarket. Do I need to spend money to buy them outside? Supermarkets even sell ginseng medicinal materials. Anyway, I haven't seen any supermarkets that carry them. The heroine's is good, there are some that shouldn't be there, and none that should be there.
