In different seasons, the items that stores, shops, etc. buy from you change and some of these items are purchased from you for a higher amount. In one of the seasons, boiled eggs were purchased at a higher price by the supermarket. In this season, you can buy 50 to 50 eggs, boil them, and sell them at a higher price. And because all these actions happen in your house, time does not pass you by and the clock does not move forward. I think you can earn up to 100,000 coins in a day.

I used to make cheese myself. I earned 28,000g in one day (cheese was a product that was purchased at a high price in restaurants).
