My wife doesn't like to have anyone in the way when she's cooking. She is the queen in my kitchen, so she always cooks alone) I only buy groceries, by the way, I recently started doing it online when I needed caviar quickly and inexpensively, and found an online supermarket with delivery
https://www.gourmetfoodstore.com/caviar/. It turned out to be a good store with low prices. So I suggest you try ordering groceries online.
